I'm not familiar with that ramp, but if it is city or county owned then OC or CC would be legal. If private property, then of course their rules.
Presuming that you are 18 yo or more you may OC on your motorcycle legally and of course loaded/hot - otherwise is would be a fancy paper weight.
We are having a small OC breakfast tomorrow morning - come on out and introduce yourself - a lot more ground can be covered in a very short time in face-to-face conversations.
BTW - take the time to look at our Forum Rules. Double posting the same question on different threads is discouraged. Don't feel badly though, it takes time to get the feel for things here. I did consolidate your 2 posts into this one thread.
Look forward to meeting you.
