Toothpaste is out.
Hairgel is out.
"Topical or rash creams" are out.
Lip gels are out.
Shampoos and conditioners are out.
Personal lubricants are... just fine.
I blink. I find I'm suddenly unsure whether or not that means exactly what I'm certain it does mean, so I google "personal lubricants" and yes, it's talking about exactly what I think it's talking about. Up to 4 oz. of personal lubricants are just fine.... practically the only liquid you can take with you onto a plane.
I think I must be losing it.
For a moment there, I really planned to drive up to a drug store, buy a 4 oz container of personal lubricant, empty it out, wash it and refill it with toothpaste.
