If you are looking to keep the surf of Summer alive in your landlocked life, you might want to try a dry version of stand-up paddling (SUP). Riding a long skateboard by Kahuna Creations while paddling yourself about with a Big Stick is the skating version of the popular water sport. As you can see, Matthew McConaughey is a fan of skate paddling; I would say I am too, but I'm not quite proficient enough at stopping yet to really claim to be a fan.
I had fun paddling up and down my street. Not only is it an upper body workout, but the motion gets your heart rate up too. As someone who is accident-prone with no prior skateboarding experience, it just doesn't feel all that safe — hence the helmet. Falling into water while SUPing is much less daunting than wiping out on asphalt. I found stopping and steering difficult, but feel these skills would come with practice. And skate paddling is fun, so practicing to gain skills would be a good time.
Here are a few more detailed shots of the board and stick.
