we placed the 4' by 8' sheets on our skates and "rode" the wood home!

That would have been a sight XD

And you could have told your parents but I'm not sure how well that would have gone down XP

Was your dad not curious about where you got the wood from? o_O

Also I always thought street skating was done in the streets and ramp skating was what you're doing here and in skate parks. I grew up skating streets (literal roads which were horribly rough where I grew up, and also the local school which was much smoother and had some pretty good "ramps" which were pretty steep, though that was overall bad because they were supposed to be accessibility ramps x_x) and there were no skate parks.

Were you coming down off the roof? O_O Or just riding up the ramp and it looks like you're jumping off the roof due to the angle of the photo XD
