We had at least 5 people stop by our site Labor Day weekend asking where to get them. When I told them I made them, they would just drive off. I do keep printed instructions handy for anyone interested. Ive given out several copies over several camping trips. Some not even at the Fort. One guy at Jellystone in Madison, FL asked about it (yes, my mickey light goes out at every campsite) so I gave him the directions to make one for his wife.
