The Cape Cod Baseball League Hall of Fame will not be open anytime soon. Definitely not by Spring 2018, and probably not by Spring 2019.
A Cape Cod Times article about Mike Sherman (Managing Partner of Total Athletics of Cape Cod), says that the brakes have been put on the 92,000-square-foot Cape Cod Training Center. Sherman said he is "aiming to get a finance team and investors onboard by the beginning of spring." The Training Center was announced to be the new home of the Hall of Fame in March, after the Hall of Fame was moved out of the basement of the JFK Museum on Main Street, Hyannis in January.
Unfortunately, this news means the Cape Cod Baseball League Hall of Fame is very likely homeless for 2018.
