Designed, built, owned and managed by Jon Sewell.
A former sausage packing plant, built by the Deford sausage brothers. Briefly owned by Baltz Brothers in the early 1980s and returned to the Deford family in a court case that reached the attorney general's office- sounds like a juicy legal situation for the right legal researcher. Possibly run by a distributor of adult-oriented videos in the late 1980s, before falling into disrepair, neglect, and re-use as a squat for trainhoppers. Abandoned throughout the 1990s and aughts until it was bought in the early teens by Jon.
Its a little more refined these days.
