Does anyone else have a specific detail duty bag. You know that "I'm gonna be here all damn day sweating/freezing my ballz off" bag. I know someone here has some genius thing they carry that I never thought of. I have the following: Water (of course) Snacks Sun block Bug spray Gatorade powder Ear plugs Small towel Cell phone battery pack Foul weather gear (rain gear, extra hats, gloves, chemical hand warmers, etc). What am I missing?
