Hey carl, we have gotten anywhere from 250-400 dollars out of a bag of mushroom corn. Since we started doing Carmel it has been toward the upper level. Good question to ask Greg, would be nice to see him post here. When you look at the applications for an event they will be very specific about what paperwork and permits are required. I don't know about the home improvemnt stores, seems like they are long tem concessionairs, just ask them when you see them. The is a new one aat the HD in Federal Way, took over when the last concession guy gave up the lease because he wasn't doing very well. Check out the forum at Vlma's Wicked Delicious KC, they have a fun blog and seem to actually have people posting stuff. Wish more people would contribute here, I know there are KC people out there but most don't like to share I guess. Good luck.
