Thirteen holes. Not nine, not eighteen. Braintree runs its own math and has since 1950. The extra four holes let you finish a round without losing the whole day. That matters to Greater Boston walkers who grab a quick game when time opens up. Municipal pricing keeps it honest. The layout won't show up on destination lists, but it was never meant to. This is where South Shore locals learned golf on foot, and plenty still do. Show up, pay, walk the loop. Some courses chase everything. Braintree stays put.
