You are looking for a small/regular size crayon box. The log is in the medicine bottle to help keep it dry.
This geocache is located on a bicycle track that is part of the Fools dozen mountainbike race occuring every year around the time this cache was made. Only kids do this short track, it is .3 miles long. the adult race is 9 to 12 miles long depending on your racing category. This race draws a large crowd to the small town of medicine park. Finding this cache during the weekend of this race may be tricky do to the big amount of muggles. The bridge in the title was put in a week prior to the making of this cache. Hope you have fun finding this cache!
