I created a summary of info about insurance that our club buys through FMCBC. If you're logged into northshorehikers.org, you can find it linked from the page FMCBC Insurance & Advocacy, which is in the NEWS submenu.
Most important point:
Our FMCBC insurance protects only against liability - not personal injuries, nor emergency rescue, nor medical costs etc, unless they are part of a successful legal claim of negligence. Only defense costs and claims settlement are covered.
