For a slightly more luxurious showering experience, splurge on the Flying J. It can be a little intimidating walking through the truckers -- who are laid over in front of the big-screen TV, IM-ing and eBay-ing on the WiFi stations, or simply chain-smoking in the common areas -- but the lot-lizard feeling will pass, especially once you enter your private shower chamber. Just $6.50 buys as much time as you need in the bathroom, along with clean towels. Shower shoes are optional, but your own shampoo and conditioner are a must. Luckily, grooming supplies and a host of other things you didn't know you needed -- including a quick shave or haircut -- can be had just beyond the shower doors. All hail the modern truck stop.
