Strings, spare batteries for tuners, pocket knife, sweatshirt, towel, huge garbage bag (if it rains, and you have to keep equipment dry), pliers, bug spray, plenty of picks. If I'm playing my fiddle: some self-defense items like paint-ball guns (loaded, to return fire), earplugs, goalie's face mask, track shoes (for running away), new insults for hecklers, and make sure that your name and home address are freshly taatooed, so that your grieving family can have sme closure, if the worse happens.Wilco in Tennessee
