We do something like this every year. Usually take my RV and tow a Jeep but with the price of gas so high it was much cheaper driving the Jeep and staying in hotels than driving the RV and staying in campgrounds. Last year spent a month in FL doing all the NWR. Did St. Augustine alligator farm rookery, Merritt Island NWR, most of the places along the Florida birding trail and the Everglades. Two years ago drove from Cleveland up to Fairbanks and Denali NP. Found that the best place to photograph the wildlife is in it's natural habitat was in the Yukon where the black bears and moose were eating right at the side of the roads. Was so little traffic that I stopped the RV on the road was able to shoot photos for almost half an hour in most places without any traffic. I will post to my website as I can when traveling. www.pbase.com/vciinc.
Traveling is one of the perks of retirement.
