Reviving this ancient thread. Has anyone found a way to practice on layovers? Thought about getting some sort of TSA-friendly training aid to use in hotel, but haven't found anything that seems worthwhile.

I've only played a few times on layovers, and of course had a blast. But with round trip Ubers and rental fees, it ends up being outrageously priced just to play a random muni without your own clubs.
