I knew about geocaching for a long time. My friends and one of my schoolmates do geocaching (in the extreme way). I always wanted to joint hem but I was rather scared to try it...(5/5 danger, abandoned mine does not sound that good). Even though when I was young I could go to any abandoned mine or dangerous place and have fun. Now I changed.
Anyway my boyfriend got himself a GPS so we started to geocache...easily reached caches but anyway we already had some fun and some really nice experiences both creepy and nice ones.
