- For me, I dress to protect myself. So the most I'll wear is heavy shoes, long pants, long sleeve shirt, leather gloves, goggles and hat ;) the least I can get away with in our neighborhood is shorts. It would be nice though to just walk off the back porch to pick a tomato and not get dressed first.
We have poison oak out here in So Cal and I've had it many a time when fighting wildland fires. I am careful when hiking that I look for certain foliage that could be harmful but I truly haven't done that much naked hiking and that that I have done has been in the desert on well maintained trails with little to no foliage around.
Be careful around it when it is burning. I have heard that getting in the smoke of burning poisonous plants can give you a reaction deep in your lungs from breathing in the urushiol which has gone into the smoke.

We have lots of raspberry bushes here that are very prickly but the big problem is stinging nettles. The merest brush of a leave is enough to give you a real sting. The good news is that it dissipates pretty fast. I've learned in my years of gardening nude is that you just need to be more careful.
Since we moved in the new house I've started mowing in the nude. Surprised the missus one day when she got home for work and I was on the riding lawn mower naked. She was jealous. As for the weed eating the yard is still to new and there are to many stickers. Have to go with pants on that.
