The East-West challenge has been around a while. An annual event, it pitted a 30 player Eastern team against a 30 player Western team. Though it hasn’t been played lately due to waning interest, it will be played this year in San Benito, Texas, in April. If you are interested in traveling to South Texas in April for a week, let me know. I have posted the flyer on this site. Search East-West.
Here is an accounting from a couple of Florida players, from a few years ago.
