I don't know if you've seen this before but it kicks ass. I was on vacation at Loon Mtn NH and i'm definately trying to get this feature in our park next year. Quarter pipe up to rail or log (i think mammoth has a log). You can slide it, spin on, hit it as a regular quarter, or gap to the other side. Switch ups are really fun. It would be even better if that up box was moved down a bit so you could slide the rail and then jump to a down box.
