Thanks for the info. I'm getting the itch to travel and my old SLR is outdated. I have Canon lenses, so it might pay to stick with them, though I've always wanted a really good long lens. I shoot mostly landscapes, not much wide-angle stuff.

I waited an hour before hitting the road. Read AgTalk (natch), answered some texts, read a paper and worked the crossword. 140 miles home took less than three hours. Two slow spots near Dayton might have added fifteen minutes?
