We did a tour of Yuengling Brewery last spring and had a great time, but i've had several people request that we go again. The tour is free and on Saturdays you get one free sample at the end. Also, you must wear close-toed shoes for the tour (no sandals or flip flops).
It is about 1.5 hours from York to Pottsville and the tours are rolling starting at 11am. I suggest that we carpool from various locations (depending on where people are coming from), hence the start time of 9:30am. We can coordinate those closer to the date. Last year we also had lunch at a nearby restaurant after the tour, so I would suggest we do that again.
Hope to see you there!
