getting married in tn on sept 22 and will be driving fron san francisco to gatlinburg. only doing this so my dog can carry the rings. would like any advice on place to camp (cheap) through the souther states (az, nm, tx, ok, ak). on the way back we will be heading on the north route. we do not have much time for sight seeing (must see the grand canyon)(8 days of total driving)...crazy?...we would fly but it is too important to have our dog along...thanks for any advice....
