haha.. that was so funny..
Last summer me and Tim were camping out by LBL with some honeys, and had a fire going.. well i shoulda known better but I had a few in me. anyway we built it on the beach of the lake and it was all little cobbles of dover chert and about 20mins into our camp fire. we had fireworks.. i had a small piece of rock stick to my lip and gave me a 2nd degree burn.
