Join Jen Messing from Into the Deep tours for a day-hike through WIlliam O’Brien State Park in Marine on St. Croix. Meet at the main entrance at 11:30 AM May 20; we’ll begin with a group picnic, hike for three hours (snacks and GORP included!), and conclude with a recap around a bonfire. Lunch and snacks are provided for free; parking permits to enter the park are typically $7/day. Attendees should plan to hike 5-10 miles.
