I don't personally know of any, but, here is a thought. I travel a lot myself and usually find myself in the same position that you are in. I have found local law enforcement very helpful. If you tell them that you are from out of town and that you would like to spend part of your trip at the range, I can almost promise you that they will went you in the right direction. For example. I was in Fort Stockton, Texas a couple of years ago and wanted to keep up my shooting skills. At lunch on the first day that I was there, I spotted a couple of city cops in a cafe. I stopped by their table on my way out, told them my name and let them know that I would be in town for a while working and was staying in a local hotels. I then asked about a place to shoot. They told me of two ranges one public and one LEO and 4-H only range, where to buy ammo, targets, etc., and about a friendly competition that they have once a month which is open to the public. I went to the place of business of the guy that runs the public range. He said that I had to be a member which was $20.00/year. I asked him how much per hour or day was on top of the $20.00 and he laughed. He said, It's $20.00 a year to belong which gives you unlimited access from dawn til dusk plus a key deposit of $1.75. I filled out the one page form, signed it, paid my $21.75 and shot pretty much every weekend and some week days the whole 4 months that I was there.
