I liked your ideas, we have a bit of a delay between recording editing and publishing, not sure if we will be able to submit for these regularly but hope to upvote, resteem and support for sure!
More ideas:
Best "not made to skate" spot
Fingerflip Challenge
Caveman Challenge
of course could have Switch, Nollie, Fakie Challenge
Help someone else learn a trick you know
Make a stranger smile with your skating in public
Still trick challenge
Consistency challenge (who can do 10 ollies/kickflips in a row the cleanest)
Carpet Board challenge
Bowl challenge
Red Curb Challenge
fast forward line challenge (best looking line played in faster mode)
slow Motion Challenge (Best looking trick in slow-motion)
I like the question idea too, like maybe every challenge should also have a question to answer. Like goofy or regular, favorite shoes, risers or not, bearings of choice, tight or loose trucks, favorite skateboard company/brand, favorite pro then & now, worst injury, trick that took the longest to learn, are any tricks easier for you in switch or fakie... etc..
Dad only learned to skate so he wasn't bored at the skate park & to follow behind with the camera, his challenge is keeping up with me! Probably not enough people here to split into adult/kid or am/pro, I would say just get started with something simple and we will learn as we go! Have a good day!
AMAZING SLEW of ideas! they are all just great I was a little overwhelmed when i was making this post worrying about ideas of how to improve it each week but not anymore!
