I agree 100% with @Bluefreedom. My mom loves 70s music. I was raised listening to it pretty much all the time. I have an odd appreciation (and love) for it that my friends my age simply don’t understand.
@Eambos – I decided not to consolidate these questions because I expected a different set of Flutherers to respond to each question. I was curious if this breakout would make it easier for each set to have a more coherent conversation on separated topics.
Urethane skateboard wheels were introduced in the 70’s and that was a big innovation over the clay and steel wheels used before then. Thats when people started to ride pools and build skateparks for the first time in history.
