I began my 42nd birthday by fulfilling a longtime ambition and skating a pool -- not literally a backyard pool, but the Nashua (NH) skatepark version, which would be a nice backyard kidney for a race of giants with its 6 foot deep shallow end, but lots of vert and real pool coping, so yeah, a legit pool (as pictured above with someone else skating).
When you're just trying to get the feel for this kind of pool -- and specifically not ready to drop in for a fast start -- it is pretty much like riding a roller coaster powered by a squat machine. Exhilarating, but exhausting. I was figuring out the pump and getting about 3/4 of the way up the 10' deep end when I ran out of gas. Playing a very long 19th century base ball game the day before against the NH Granite in which probably 50 runs were scored didn't help my skating stamina.
It is unbelievable how much great skateboarding terrain has been built in the past ten years. I'm glad I suddenly realized what has been hiding in plain sight.
