Thanks, everybody! I ran a pocket query, but it gave me way too many. I even shortened it to only include those from OKC to Omaha. I think I will use the smart phone suggestion and open it up when I see a rest area. I hope you are correct that there are caches at every rest stop. Tell you what... if I stop at a rest area without a cache, I'll drop one off. Nope, can't do that. Can't maintain it. Oh well. Thanks for helping, everyone!!!
