The Austin Beer Trail of caches leads you to different breweries, brewpubs and adult beverage establishments in the Austin area. Some places have happy hour tasting sessions, and some do not. Please check their web sites for each brewery's hours of business. Most of these caches will be in the public domain, and will be kid friendly.
This cache is close to an event that happens the first Saturday of the month. Me, and about 1000 of my closest friends, desend to this complex on the first Saturday of the month, for the open house and tour that Independence Brewing puts on. If you're not there for the beer, then I would suggest avoiding this high muggle day.
This cache is a quick park and grab. Watch out for the lizards. There's only one place it can be.
