, a few tealight candles & a couple sm. flashlights (just in case we're ever there during a storm where the power goes out), hats & visors and goodness knows what else!! My inventory list has about 120 items on it!!! I keep track of expiration dates if they apply on my inventory list so I know when something needs to be replaced.
You will LOVE the convenience of being able to just pack a few clothes & go!! If we have 2 trips planned that are relatively close to each other I sometimes will leave (unopened) packages of crackers or snacks or waters (IF they fit)!! I have to sit on the lid while DH applies the zip ties in order to get it locked back up now!!
