It's along the south side of Route 329 in Northampton, PA. If you've ever gone up past the airport to Howertown, if you're heading north you'd make a left onto Weaversville Road, follow that to the end, make a left onto Route 329 and it'll be about a mile up on your left. The massive concrete silos are very hard to miss.
Be well. Do good work.
