Tons of food at the food stops along the way, rebecca! In case you want to take less of your own and have room for that camera of yours. The standard joke is that STP is the only 206-mile ride where people can GAIN weight along the way because they're so well fed. My favorite was when the REI stop had boiled potatoes and salt.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
