When we were brand new to caching, a few months ago, we were in a town that borders with Mexico. At this time we didn't realize that sometimes you can't get to a cache from where you are. We were on a dirt road and all of a sudden there was a Border Patrol vehicle behind us. We stopped and talked with the officer, explained what we were doing, we had print outs and hoped she wouldn't ask our names, our daughter works for customs and we wouldn't want to embarrass her. She told us how to get back to the main road and we finally found the cache.
