Thanks for all the info.
I had no idea there was etiquette in the park, since I just started to ride it. The two major places here in SoCal are Bear Mountain and Mt. High, where the whole place is a park, and nobody hikes.
The one time I saw a small park section was in Alpine Meadows in Tahoe. I had no idea people hiked up to ride the 50-yard park they had. So the last run I did that day, I was just bombing down the mountain and rode right into the park. I managed to hit one box, then ate shit on a jump.
That was my bad, I didn't know there was a calling system and such. Do you fall in line?
Ive been riding at bear for like 5 years now and usually at bear no one trips out if you bomb down as long as you bomb down without hurting or messing up anyone, because usually hikers take forever to go ! and if your bombing it takes like 3 seconds to hit any feature and be out the way.
