Only ridden on pavement so far, eventually will go off-road. For carving, which is what I love, wide, smooth and relatively quiet streets seem to be ideal.
Suburban streets and Retirement Communities are ideal, I avoid morning and evening rush hour during the week, and go early on the weekends. The Retirement community has a 2 mile loop, and I maybe encounter one car on each loop.
There is a state run center/town near me that is shutting down as well. Looks like you could film a post-apocalyptic movie there, so the streets are mostly empty.
I avoid any place with car and pedestrian traffic. When I encounter cars, I immediately yield the right of way and pull over. Same thing with the police, I try and avoid them and if I run into on I immediately pull over and wave. Pedestrians seem for the most part very interested and I always make sure to smile and wave.
