I'm pretty sure Comcast does carry Cool TV in Bristol County, MA on channel 290.
It's also amazing that Full Channel carries it. Has anyone ever heard of this small cable company? It is a competitor to Cox in Bristol Co., RI, but it has actually served the area for 25 years. I remember in the early 2000s when Cox was buying out all RI cable companies, the owner of Full Channel refused to sell his cable company. But not all customers were happy with it, so Cox decided to come in on their own. Since then, Full Channel HAS upgraded, but not by much. However, I believe they do something with their system that no other cable company does, though I think they should. With most providers, you have to go to a different channel number for the HD (channel 10 on 810, channel 12 on 812, etc.) With Full Channel, if you have an HD receiver, it will automatically be in HD if you type in channel 10 or 12. I think all providers need this, because I think THIS is one of the reasons why most people don't watch HD even if they do have the capacity.
