As far as burrs on socks when geocaching in shorts, go to Walmart or any other big box store. Go to the women's clothing department and buy the largest box of knee-high nylons you can find. I personally prefer something called trouser socks, they are a little stronger. Pull on your regular cotton or wool socks (I prefer knee-high acrylic ski socks to protect my lower legs from stinging nettles, poison ivy, cuts and scrapes), pull the knee-high nylons over the top of your regular socks and head out. When searching for a geocache not in the woods I push the socks and nylons down around my ankles. At the end of the day, you can either brush the burrs off (they do not stick to nylons near as bad as cotton or wool socks) or just pull the knee-high nylons off outside in and throw them away. You can even pull the knee-high nylons over your shoes to protect your shoestrings. They will not last long walking on them but when purchased in bulk they cost as little as 50 cents a pair and I consider them consumables. I spend much more for gas on an afternoon of geocaching. By the way, I am male and this beats spending an hour pulling burrs out of my socks one at a time.
