There is an additional resource on the website now for finding days and times to play – Joe Spada’s List. Look under the “Play Times” menu Play Times/Organized Play Dates/Times/Sponsors
Note that several groups are “Invitation Only” which means don’t show up and expect to get to play – Check with the group organizer in advance to find out if there are open slots – many of these are just small groups of friends and don’t intend to expand.
