I know how people are with their mugs at home. I'm the same way. Your mug is your mug and cross contamination is unnecessary and unacceptable. For most of us, that sentiment also translates to camping, and for me, that means always bringing along the old L.L. Bean mug I've had for way too long. That thing has been all over the country, holding some insanely bad cups of instant coffee, tea, whiskey (notice the Coke bottle full of bourbon?), noodles, and often enough, all of these things at the same time.Y'all got something special that's always along for the ride?
