Use your parking brake so it doesn't seize up.

Gear is perfectly fine for small incline. I park that way at home for 16 years. And I don't park on steep incline anyway, nobody should unless no other way.

I put a brick under the tire. Next question.

Do you guys use hand brake or gear when park a car?

Eye contact is over 9000, I bet.

Do you ever get on the treadmill next to them and walk slow without breaking eye contact?

Haha. No, why would I? As I said I'm not starstruck. Had the chance last spring to get a pic with Karl Sanders when Nile played in town but didn't ask him
