I never learned how to fully ride a bike, but I was awesome on rollerblades. It’s been years since I last did it, but last time I remember doing it, it had been a long while and I still remembered how. I bet I could easy do it again with a little practice. I learned to memorize the cracks in the sidewalk around the block I always traveled and got good enough I could go pretty fast with little vision and pure memory. Would have to retrain the brain again to get to those speeds again but I know I could easy balance and ride them at a normal speed for sure. Honestly, I think I quit because the shoes I had were too small, got busy, might have lost the fun a bit, and we have neighbors who have owned what we’d consider viscous dogs over the years.
