Lots of us do it.
I was widowed in 1970. & started keeping my own dogs once I got off of a travel job in 1979. Since then I've learned how to enlist neighbors for the dogs when I traveled for work
I am now 73. Partly because of need for hip replacement I didn't do my biggest trip in 2014, but did so last year, after that surgery. I drove from The Martimes to Skagway, AK and back late summer 2015 through early fall 2015. 18,000.00. Dogs travel with me on personal travel.
& developed night driving problems with the cataracts during the trip. Op to happen this spring.
I previously lived in Newfoundland, thus, that trip made me a sea to sea person. I haven't updated my map in signature images yet.
Go for it!
