When I was in high school and college, I was part of a group that went spelunking (crawling around in caves). On a number of trips, my dad and my sister went along as part of the group. The funny thing was that my dad would come out of a cave almost clean and the rest of us would look like we had been crawling thru the mud (we had!). At one point, we even did some cave mapping to extend info on the previously mapped parts. I always enjoyed those "family" caving trips!
