The good thing is that it is a public group; you can read posts there without a Facebook login. Here's a good summary of events upcoming in the Austin area:
- Tuesday Jam league at Pinballz (original location), starting the first Tuesday of each month and running for 4 weeks
- monday night pinball at Pinballz (original), a "10 strikes" format starting at 7:30PM
- International Radical Cowabunga Day, matchplay tournament at Pinballz on the 5th Tuesday of any month that has one
- Batman ’66 Premium Edition Launch Tournament @ Pinballz, May 1, 7PM-11PM
- May the 4th Be With You! Star Wars Pinball Tournament @ Pinballz, May 4 (obviously) @ 7 PM
- Buffalo Billiards monthly matchplay on Sundays (next one on March 25) at 1PM
- Bat City Open at Buffalo Billiards June 22nd-24th (doubles as the finals for the Texas Pinball League summer round)
Of course, all of those are far from Liberty Hill, but maybe you can make it in to town for some of the one-shot tourneys.
