The Ridgefield Planning and Zoning Commission is slated to take up a proposal tonight to turn an historic Main Street home into a bed and breakfast.  A special permit application has been filed for the two-acre property next to Keeler Tavern Museum.  It's across from Ridgefield’s historic fountain.  The home was built in 1740 and has 8 bedrooms and 9 bathrooms.  Ridgefield only has one bed and breakfast, The West Lane Inn, which was recently sold.
