Black Friday shopping is a hallowed holiday ritual for some people, hell on Earth to others. If you fall in the latter camp, why not follow REI’s “#OptOutside” lead? The outdoor-gear retailer is bucking the system this year, closing on Black Friday and urging people to get outside and do something active instead.

Brian Harrower, general manager of the REI store in Bloomington, was hoping to play pond hockey if the ice cooperated, but is now taking his family for a Fort Snelling outing. Other REI employees will be doing everything from geo-caching or rock climbing to renting a boat and “sleeping off my Thanksgiving dinner between two trees.”

Some ideas for opting out of the indoors Friday:

While shoppers are trudging through packed mallways: Stretch your limbs freely at any one of Minnesota’s 76 state parks and recreation areas, which are offering free admission on Black Friday. The popular Pike Island loop at Fort Snelling State Park is just 3 miles. Complete list at dnr.state.mn.us

While they’re numbly riding escalators like the walking dead: Shake it off climbing stairs with the November Project, a group of die-hard enthusiasts who like their fitness al fresco and free of charge. They’ll be working off the turkey at 6:30 a.m. Friday at the University of Minnesota Boathouse, 550 East River Pkwy., Minneapolis. All are welcome to work out at their own pace, no matter their age or fitness level. november-project.com/minneapolis-mn
