Input: Text: as with most this happened years back. i was in boy scouts in junior high and we went on a trip backpacking by lake superior. one of the days we wanted to kill some time so we went into this small tourist town to get some things and went poking around the lake.

by lake superior people will often stack the smoothed rocks and create art and towers balancing the rocks like [this](http://i.imgur.com/l1b19ih.png) sometimes getting them to be 6 to 7 feet high. 

so we come across a beach full of these rock towers. being dumb young kids we don't know any better and think these would be fun to knock over. so we proceed to kick over and throw rocks at these stacks until none of them were left standing. we then make our way back to the suburban to wait for the rest of the group. 

in the meantime a bunch of yuppie art people were pulling up to this beach to look at these stacks and finding them all knocked over. eventually they figured out it was us because someone saw us and we got reamed out for destroying creations that took artists weeks to create.
