The following rules apply to all of the ISR functions:

No Drugs, No Booze, etc. This is a sober event for all to attend.
No Dogs! If you insist on bringing your pet there are multiple animal lodges available for your pet.
No streaking (Thanks to Ben and Duffy)!

Many of our host venues have their own rules. We ask that our participants respect these rules, so that we will continue to be welcome:

Make sure your campsite is cleaner than when you arrived. No littering.
No parking of cars & trucks by the tents unless you are unloading. Park cars & trucks at the top of the hill near the entrance.
No fires or smoking unless in a designated area. Police up your cigarette butts.
