Go full minimum. Get your gear down to the bare necessities for the evening. Let her carry a few of the bulkier/more embarassing items. And get some of the hidden pocket pants like the Dokker tech khakis or like SeV pants.

Put the rest of your gear in the car... it's like 50 yards away right? Make it a situation awareness exercise and look around you for items that you could convert to your needs in haste. <img src="/images/graemlins/smile.gif" alt="" />
