The second annual Lake Monster Bash brings the joys of the fall season together: crisp outdoor weather, festive costumes, and the overconsumption of delicious candy (or beer, if you’re a grown-up). Spend time on Lake Monster’s open-air patio, or head inside the heated, spacious brewery if you haven’t acclimated yet. The party will include a costume contest, so go all out for prizes. Five special beer infusions will be on tap, and with a ticket your first pint is free. Al Church and his soothing pop will headline, and the stacked lineup also includes pop-rockers Solid Gold, Field Report, and Americana groups the Pines and Dead Horses. Advance tickets are available at getknitevents.com and at the brewery. 21+.
