We've ran into people a few times. There's always the awkward are they cachers or not? First time the other group simply said "it's OK we're not muggles!" Got a good chuckle out of that. Next time my daughter and I were going for FTF on a few new caches and saw another car drive up, I thought we could either have an akward silent walk or work together. So I said, " I think we're both here for the same thing" They were more than happy to walk along with us for an hour to do all these caches. It's nice to hear other peoples experiences and see faces to the names in your area. On the other hand, I have a cache nearby my house so I often glance as I drive by. One day I saw a couple obviously looking for the cache, so I thought I'd have a little fun. I drove up, parked right beside them, walked up to them and sternly said, " what are you guys doing" implying they were on my property> They looked up and didn't say anything, I don't think they knew what to say, then I laughed and said who I was and that it was my cache. Everyone had a good laugh.
