Flew up to Lake Winnipesaukee NH yesterday, 40 knots going north, 80
knots returning.

It's been quite a while since I last flew a J-3, but IIRC, it cruises
at 73 mph. What was your ground speed returning, and please put a
plus or minus sign in front of the number. ((:-))

Those were the ground speeds, read off the GPS.

OOOPS! My fault; I misread those as winds.

Those wings will be 60 years old in September, and I don't care to strees
them.

Very wise.

I use knots in the Cub because the cruise is typically 60 knots, which
makes it dead easy to mark off distances on the sectional.

Yeah, knots work better.

The width of my thumb is ten minutes / ten miles.

Wow! You have a very muscular thumb! Mine is only seven.
