There are a couple of parks close to my house. They have stairways with switchbacks. Those have been helpful. Respect park goers as the stairs were built for them. There is also an abandoned housing developments close by. There are a variety of drops and elevation changes between lots. BMX riders use it a lot so I have some ready made trails, sometimes I just try to see if I can hop up a grade. I live close to the end of the world, so vacant lots are easy to find. Then there are trails as well.

Biting it and biffing happen. I try to avoid biting and biffing. Practicing can help.
