Placing a cache in or around poison ivy. I've located two caches lately where the only poison ivy around was right at the GZ. It's easy to get "target fixation", becoming so engrossed in locating a small cache way out in the woods that I fail to notice the evil stuff until I've already walked through it. Then I have to carefully strip and wash everything, including my shoes and laces, the minute I get home. So far, I've been lucky. I recently read a log where a woman had taken her granddaughter to find her first cache. When I later arrived at the GZ, I found poison ivy all around it. That little girl may well remember her first geocaching experience for the wrong reason.
