$1I made a couple trips by myself, but most of the time my wife goes with me.
The solo trips have never been a problem. The airport staff, the airline staff, and even my fellow passengers have all gone out of their way to make sure I get to the next gate for my connecting flights. The white cane works miracles in an airport.
Headed to Pennsylvania next to see my daughter, then back to Tennessee this summer to water ski. If the drought ends I'd like to visit Yosemite Falls. Come to think of it, it's been far too long since I've visited a waterfall. I should make some plans.
