We have these harry spiders but the big males are harmless and they are actually beautiful creatures. The females are almost hairless and will give a nasty bite. During the summer rains they come out at night like your earth worms do. I have never picked one up but I have seen many people do that including little girls.
Everytime we go camping we put a tarp under the tent and when we break camp a pack up there is almost always a scorpion under the tarp. This is a Vinegaroon Texas "whip tail" scorpion. Mean as hell! We have the variety of vinegaroon that has a transparent body and it is the ugliest critter on earth! You better go put on another pair of wool socks!
