I've just podged a lass at 58 and enjoyed it, the lass before that was early 20's and I enjoyed her too.
I'm neck end of 50, late 50's don't seem that drastic to me, neither does early 20's
My age range is 20 to 60, that might not suit all but that's what I like, it's the variety that I find the best thing about punting... age, race, colour, build. If I've got a certain lass I want to punt then off I go.
