We use both Harvest Hosts and Boondockers Welcome (now the same company, but keeping things separately). We've only full-timed since April, but have gotten our moneys worth. Four stays with different Harvest Hosts, including breweries and a Lavender Farm. We prefer Boondockers because most places we have the option to stay multiple nights, and many have hookups. We just finished a six night stay in Centuria, WI at a 'hobby farm'. Super friendly folks, 50 amp power, and water. We visit an aunt in Luck, WI., just 10 minutes away. We're already planning another trip next spring.I have been able to make a few same day stops, but since we're full timers, I have a pretty solid itinerary planned in advance.
