The bus doesn't run to Bridgbury. Bridgbury isn't named in any tourist guidebooks, except as a dot on the map midway down a roundabout side road. Not many people visit there, and those who do report that something they couldn't put their finger on made them reluctant to stay.
Some people blame the locals.
Some others say the locals are perfectly charming, the epitome of rustic England; it must be the sour atmosphere from the nearby bog.
