Don't just show up, and think you're going to be okay. Practice going light at all the events you do this season before going to GAC. Make a written inventory of all your stuff before your first event. This includes food. Within twenty-four hours after that event, remove from you list what you didn't use or didn't really need. Repeat.
I do two airplane trips a year to events. All my stuff fits into my knapsack and a large duffle bag which is about twelve to eighteen inches deeper than the standard size. If you cannot fit all your personal stuff into a knapsack and duffle, you've got too much stuff.
I often bring a batch of hardtack to faraway events because it increases the odds that I'll have decent meals. Remember there are stores in Gettysburg and the surrounding area. Purchase a bag of salad. Since I use vinegar at events, I'll add some to the salad. (Have a swig of balsamic vinegar with every meal during the weekend. Your stomach will thank you later.) Buy an apple while you're at it. Get a bag of rasins. Purchase a half pound of bacon per day in the field. Upon arrival at the site, find a fire and fry all your bacon. Eat your salad, hardtack and apple while frying that bacon. Have some raisins for dessert. Now you can snack all weekend out of your haversack and scrounge when opportunity presents itself.
Try to use period solutions to modern problems. For example, make your morning coffee before you go to bed by putting ground beans into your boiler and filling it to the top with water. Let it seep overnight. You can place it on a fire in the morning. When it's hot, it's done. It's like instant coffee only better. You can drink it cold if necessary. It will be the best coffee you have all day. The two most difficult things about premaking coffee are (1) taking the time to do it and (2) stashing the boiler where some Jonah - or you - won't knock it over in the middle of the night.

"I take [this hobby] seriously just as any golfer, hunter, or fisherman would take their hobby seriously. You whine that "hard kewls" are what is wrong with this hobby, but I digress. In my opinion, the major defects in our little world consist primarily of the clowns and jackasses who don't take it seriously." - Mike Phineas, 2 August 2013.
