Too old now.
Since I celebrated my 66th birthday just two days ago, 70 is far too close! After all, it was only last year that I was finally able to park the Rocket in the Senior Parking spot at the grocery store. As for a trike? When I can't ride two wheels I will probably trade for an ultralight aircraft.
Bad news this year... I got selected for jury duty from the first of July through the end of the year. Now I have to ask permission before I can leave town for more than a couple of days. Civic responsibility, you know. I may have to plant some tomatoes.
