It sounds cliché to call Tentrr "Airbnb for camping." But it's also pretty accurate. This app/service lets you find and book thoroughly vetted campsites within just hours of major cities. Each site offers amenities like hand-sewn expedition tents, air mattresses with featherbed toppers, Adirondack chairs, fire pits, and grills. In other words, it provides a happy medium between "glamping" and roughing it, and will be expanding its reach beyond the U.S. Northeast in the coming months.
