I don't travel in normal life or to tattoo but I know I would be an over-packer. lol
What I wonder is, what exactly do you pack and what do you rely on getting wherever you're going and does it depend on weather you're guest-spotting or doing a convention?
The obvious is - Machines, power supply, foot pedal, clip cord, inks and probably disposable tubes and needles. But what about all the other disposables?
Also, for those that don't travel too often to tattoo - Do you feel out of your comfort zone? I ask b/c I'm an "everything has it's place" type of person. Anal, anal, anal...lol
