Has anyone encountered problems cashing travelers checks while on a road trip thru the good ol' USA? I'd prefer to take travelers checks along on a trip from Milwaukee WI to Yellowstone National Park but the bank offered the option of a prepaid travel card. Now I'm unsure which is better. I usually don't use plastic, even at home, and lean towards the checks but have heard that they may not be accepted in all places anymore. Please offer any opinions you might have on the subject or experiences you may have had. Thanks.
