Unique Bachelor Party

Ok...here`s the deal, I`m planning a bachelor party for a friend of mine. Sounds pretty normal right? well here`s the catch...he`s extremely religious so no alcohol, gambling, strippers or anything of the sort. Also....the wedding is in an areas i`m not familiar with so i don`t know of other options. Anyone have suggestions for something to do in the St. Louis area?? thanks!
