I have had a number of you ask about the taping of the caps. This is not a big deal but in Ohio many of the shows insurance underwriters (mine included) require the caps be taped . All this is is an 8" piece of electrical tape wrapped around the cap and the neck to prevent it from being removed during the show so someone doesn't accidentially ignite your tank by smoking or a spark. Boy from the reaction this was really interesting. I assure you all this is not a big deal. I am more worried about getting enough fire extinguishers. I have quite a few responses so far so hopefully I don't have to bring a bunch. Thanks again Ken
