Does anyone want to discuss stuff of the 70s,example old school skate boards,same great stuff on e bay?

I typed n retro skateboards and was suprised to see what came up,somebody remember cryriptonic wheels and the old style trucks,i saw a great skateboard on there,starting price was £40,was in fantastic condition,it had been hanging up in a skateboard shop for years,i also remember the ones with the small engines on but they were way to expensive...great..leave comments ...
Answer
I liked the ones with tractor tracks for getting through sand and mud when the wheels would bog down. with that motor/engine on the back, one could sure plow through the snow too.
