Surfing Waves

I already have an Eastside to longboard to class. but I would like a mini board that I can ride when the weather is crap, and something that is small enough I can strap to my backpack when I am on the train. Does not have to be anything fancy just to get the job done so I dont ruin my nice board.

Thanks!

Salt water will rust the bearings but you seem to have lost yours!
