Not interested in the domains, but purely for the name, "bigbenddonkeys" I shall give you a bump.
there's a whole story behind those domains. In the Big Bend State Park in Texas, they were killing feral burros. There was a huge public outcry to stop it, and now they are trying other management methods. I figured it was a good niche, and maybe a way to sell t-shirts and bumper stickers, but I never got it going. I also have a FB page that goes with those domains.
