Paul, thanks for the welcome--I certainly look forward to the day I know enough about the TM to be able to be helpful to someone else although it will surely be awhile until I can do anything except ask questions.

And, Mack, I really appreciate the heads up on the construction around Lexington--I did this same trip in June, and 75 was a construction mess then, too. (I know they have to do it before winter sets in but it really gets frustrating sometimes, and is one reason I prefer weekend travel. but this time, I dont have a choice.) So, thanks, I WILL indeed keep the tank full and am allowing 2 full days for the 700 mile trip between the Ga mountains and Ann Arbor
