I wrote 146 and Millbury, not Leicester. You might as well include a ton of other "landlocked" towns there as well, such as Paxton, Holden, Rutland, etc. At least Spencer is right on Route 9. Wait, so is Leicester. You just need to drive through Worcester to get to it, as was said. You could also head up Route 20 in either direction from 395 or from 146 and find some spaces. Anyhow, 146, and some side roads just off 146 has a PLETHORA of older mill or factory buildings, many for sale/lease, and they want people in them. There's some buildings in Sturbridge, but probably overpriced. In particular, I'm thinking the one where Bron's was. Again, Blackstone Canal/River area is rife with old mill buildings.
I only mentioned Worcester because of the large number of available factory buildings, AND, LaRocca Gun Works is in Union Place. Over by the Gun Parlor are a lot of old factories also. Wouldn't it be a hoot to put in 80 gun shops next door to them. Ha ha.
All these towns claim they want business and tenants, so see if they will put their money where there mouths are at.
Wow, that would be awesome! Probably prohibitively expensive. How about Rotman's, which just went out of business? Divide that up into individual spaces. How bad do they want or not want business?
