No enclosed pit, just a "man hole" my hubby brought home from work (underground construction). The party is going to be in the evening (after care hours) so I dont have to follow "safety" regulations, parents are invited and their are only three little boys. All the boys do camping on a regular basis, our family (hubby and kids) have been camping and "bon-firing" for years. No, these little boys are def familiar with the rules of fire and such. Plus....my entire idea was to gear toward them being big boys now. (ready for school) and told them because it is not daycare, we can do ALL the fun stuff like, the fire, the trampoline, we will even have a big FIREWORK for going to school celebration.!!!!!!!! Now the only thing I have to hope for is NO RAIN!!!!!!!!
