When you're old and cranky buses are not a viable option. As to flying, we do take livery type service to the aerodrome...thats not the problem.
The problem is getting to the airport what seems like a day and a half before gate time, the interminable lines to heck in, go through security, repack the carry on and then wait 60-90 minutes at the lounge. Repeat at the connecting airport, and, likely, miss your connection. A trip to the local greengrocer seems to be the most traveling I'll be doing...I can hardly wait for the excitement of squeezing those melons.
