Going to Island Park, what areas to ride?

I've been to IP for 2 years in a row but never really ventured anywhere far off the beaten path.

I've been up to Keg once, and it was some of the best riding I've ever had.

Now that my friends and I all have mountain sleds, we're looking for some places that are SAFE with good snow to play around and are relatively easy to find your way back from

We're not interested in super steep highmarks, just some nice play areas.

Can anyone lead me in the right direction? If you would prefer, drop me a PM. We'll be there for a week, so we have plenty of time to explore. We're all equipped with avalanche gear as well.

Sorry guys, I thought there were riding areas around IP.

I'll stick to the trails and eat granola bars instead. Does anyone remember the proper hand signals?
