While in Yosemite we had coverage in the valley and through a few of the peaks.
As for Ray's, the place is still there. They even had and small ad in the hotel directory in which we stayed. But by the time we were ready for dinner it was pretty late and we were beat. We opted for beef jerky and chicken salad sandwiches (always a dangerous choice) from the Conoco gas station off I-70.
I said it before but I'd like to say it again. Thanks to all the good folks at roadtripamerica.com. Everyone had great advice (yes, even where to eat - regardless of whether I took that advice or not :) ). This forum, and the memers, made the trip a heck of a lot easier.
Thanks again. I see another road trip in our future and will post messages and questions as the times draws near.
