There aren't any civic organizations (Lion's, Rotary or Optimist) over there to work on fund raising?
There are, in fact the ones you named, but the BandG Clubs of Southern MD liked to go it alone.
Remember, it's not just the North Beach club that's closing but also the facility in/near CRE and the one in St. Mary's County. all the same organization.
In fact, CRE was where the idea for a club originated back in the 90's. North Beach got it because the Town government was able to tap into County/State/Federal grant funding to build the building whle CRE had no standing for those things and Calvert County wasn't much interested.
In addition to the grants Calvert County kicked in around $300K, the state threw in as did the Feds. North Beach built the building and the Town's taxpayers are on the hook for around a $250K mortgage on it.
