Mail a printed visitor guide to the regional drive market

Buy a mailing list of households within a few hours' drive of the destination, and send them a printed visitor guide highlighting one season's worth of activities, timed to arrive a few weeks before that season starts. Include a code so response can be tracked separately from other channels.

Why it works: A physical guide sitting on a counter gets picked up again when a household is deciding on a weekend trip, unlike an email that gets buried.
