Well in my case the model is only a Fox .35 stunt model and a .15 size, so they don't go fast and I am not likely to get badly cut, if I do I have a cell phone. I would worry about the lines wrapping around someones neck worse than getting hit, though I suppose it could be bad if it hit someone in the wrong place. The area is lined with trees so it would have to go straight up to go very far. But I suppose I should look for a thong. Maybe Fredricks? Also may I keep my pants on?
