Wish I could help, but I can't fit a road trip into my schedule right now.
You might try posting on www.craigslist.org. Thay have sections for every major city and you might be able to find someone who is planning a trip that way and wouldn't mind bringing the dogs. Honestly, I can't imagine you getting a much better deal than $120 though.
I'll look. Thanks. I just paid 800.00 bucks for them so another 120.00 is hard to swallow. Especially since the guy is going from Denver to Phoenix anyway. I'll figure it out.
