Answer	—	A: Risk of category three sunglasses when skiing Am I putting myself at risk of retina damage? NO The category rating on sunglasses has to do with how transparent the tint is or is not. UV protection on sunglasses is clear. To prevent retinal damage you should buy high quality glasses with UV-400 rating. Category 3 would be perfect for skiin... (more)	—	almost 5 years ago
Answer	—	A: How to protect yourself from horses? placed a hand in front of himself and the horses stopped! Brave and perhaps foolish. Horses (especially dominant males) will charge a perceived threat, and they are big. They know how to protect themselves and their band. I suspect that these were domesticated and chose to submit to a commandin... (more)	—	about 5 years ago
Answer	—	A: Is a soft board or a hard board better for a beginner surfer? Should I start off with a soft board or a hardboard? Foam board for sure. Primarily because an early bad experience (e.g. injury) could deter a learner from continuing to try, and if you get hit by a traditional board you will feel it. They are also really fun to ride, they float well, they padd... (more)	—	about 5 years ago
Answer	—	A: Are there statistics on how often CPR on someone who has been struck by lighting works? No actual numbers here, but according to the American Heart Association (AHA), patients who receive immediate aggressive bystander CPR after cardiac arrest due to lightning strike actually have a decent chance even without external defibrillation. This was a surprise to me, as I was always taught th... (more)	—	over 5 years ago
Answer	—	A: First timer-family going to Yosemite - do we need permits to camp and hike? You can backpack from the valley (up the Mist Trail, or the John Muir Trail) to a Half Dome (HD) "base camp" area called Little Yosemite Valley (LYV), where you would bivouac in a site overnight then hike up to and ascend HD the next day. Bear canisters and special toilet arrangements are not require... (more)	—	over 5 years ago
Answer	—	A: Lead free brass fittings on potable water hoses Check with a recreational vehicle supply store, they should have hose fittings such as tees and wyes (perhaps plastic rather than brass) that are safe for potable water. (more)	—	about 6 years ago
Answer	—	A: What's the proper way to establish a triaxial connection with carabiners? You could use a triple butterfly knot, some call them alpine butterfly loop knots or simply multi-loop knots. They can be tied with single loops, double loops, and triple loops. No collection/rigging plate needed and simple to tie. photo courtesy of dave@Layhands.com (more)	—	over 6 years ago
Answer	—	A: What is the rather large bug with a green body, black stripe down the middle, 8 orange legs , two large antenna and large chompers? That looks like a Vinegaroon (not a camel spider), at least that's what my dad called them. Common in the desert SW. They pinch and bite but I don't think they are venomous. They do spray vinegar at you, hence the name. (more)	—	over 6 years ago
Answer	—	A: What should I look for in throwing knives? You want knives that are not easily broken by repeated (repeated hundreds of times) misstrikes. You will notice that knives labeled as "throwing knives" at retail are most often free of any bolster, guard, handle scales, etc. That's because those things will be destroyed in the learning process. The... (more)	—	almost 7 years ago
Answer	—	A: US Military's standards for how long a soldier can go without food? I see that nobody has weighed in on this, I think because there is an old saying that "an army marches on its stomach" (N. Bonaparte). The armies of the world would probably focus more on how to get nutrition, rather than how long it is ok to be without. Due to physiological differences (I'm not a do... (more)	—	almost 7 years ago
Answer	—	A: camping equipment testing if no yard I live in the city; to prepare for my Sierra backpacking trips I jam all my gear in my pack and take off walking, increasing distance as my endurance increases. I stop and eat lunch from my pack, using the actual gear. I pitch my tent in the yard at home when I get back (you can do this indoors) and ... (more)	—	almost 7 years ago
