Bay seniors now have another sport well matched to our reduced pace of activity. SUP (Stand Up Paddling) is paddling along on flat water, never having to think about catching a wave. Boards are up to 7 feet long and the speed is as fast as you can make it. The appeal of this sport escapes the Geezer but in case you are interested there are lessons to be had in Larkspur and San Jose, Alameda and San Mateo and, inexplicably at Clay and Taylor in San Francisco. Prices start at around $90 per lesson.
