I just purchased an American travel mahjongg set from Amazon. The tiles are the size of a thumb nail and clear racks are included. It's imported from China and the case(s) have a strange smell, so I am soaking them in hopes the odor vanishes. If not, I'll find another case. The weight is @2.5 lbs. $40.
Based on roll call and FB posts, there is a good possibility to meet other players on Summit next month. Eclipse and Apex I am sailing with friends who play.
