I had my first caching trip last weekend - borrowed a friends GPS, that turned out to be dud. Needless to say, we failed to find the cache. Anyway, as we arrived, two people were getting in their car (this was the middle of nowhere). I was surprised at my reaction - I felt very 'shifty' and a bit embarrassed!
Maybe I need GC assertiveness training so I can stand proud and declare to the world "My name is Chris, and I hunt for plastic boxes!" I now have my own, used but working (Thanks ebay!) etrex Venture, and as soon as it stops raining my daughter and I will resume the hunt where we left off. I will attempt to greet strangers with a smile and an enthusiastic hello. After all, 'muggles' are just cachers without a GPS!
