Goodmorning dear @riverflows.

I am a skateboarder myselfI have been skateboarding for almost 14 years and I totally feel you.
When I feel frustrated,anxious or everytime something is bothering my ehad too much,I grab my board and just roll.I don't care where I'll go,I just want to feel that feeling of freedom you described.To isolate my mind from all the things that don't really matter much and enjoy myself.

Also,freedom for me is travelling in mountains,small roadtrips even if it's a small village 10 km away from my city.
Freedom for me is everything out of the oorinary.

About Dtube upload,I am so glad you gave it a try.
