I have skateboarded off ramps, not that i skate but I like to try things out, and I stopped doing that after falling down 3 times very hard and hitting my head against the ground two times.. i was pretty broken all over but after the skate day I got very good at ollies, gotta say, i have talent ... But the fallings vere pretty bad, i wouldnt rule out another concussion
Back when I skated boraded we had to build our own they didn't exist, we made them from old skates and piece of wood we took off of construction sites.
I skated a lot I used to hit the skate park at least a couple hours a day...but I slowly stopped as I got older...I will still skate on occasions, like teaching my nephew how to ollie and what not.....kind of miss it at times, the injuries ob the other hand, not so much.
It would make my traveling in the university campus so much faster.
