It's a blast - 45-60 MPH on winding back country roads in Virginia. Nothing scary - just relaxing like in my TD or hopefully my Speedster one of these days. You only get old when you start acting like an old man.
On the contrary, you know you're old when you start acting like a young man...and it hurts! That's usually at about 70. I can personally vouch for that inasmuch as my 76th is in 24 days. While I can still put my speedy through its paces on every back road twisty in northern CA, anything over 200 miles a day is called "elder abuse!"
P.S.: For what it's worth...I made my last military static-line parachute jump 10 years ago this July 4th (3 days from now) and I "gawrantee" it will have been my "last" jump. Not so much because I've gotten old, but I figure I've "Been There and Done That" enough times that I've earned the right to look for softer landings in life.
