Folks at the White River Valley Museum are calling the midsummer night’s event at Mary Olson Farm event “Farm Snooze.”

But don’t let the name fool you. Because long before any boys or girls or their moms and pops let a single lid droop or cut a single z, they’re sure to tucker themselves out with good ole’-fashioned campout activities, like scavenger hunts, field games and a wienie and marshmallow roast.

So come, families, come one and all, pitch a tent and spend a fabulous, unforgettable, magical night under the stars, from 4 p.m. to 8 a.m., July 21 and 22 at the Mary Olson Farm just north of the Auburn Golf Course on Green River Road.

“This is the first time we’ve done anything like this at the farm,” said Rachel Burrum, curator of education at WRVM. “We’re trying to have a family campout where families can get together and have a safe place for a camping experience.”

REI will provide free gear rental for those in need and even a spot of breakfast in the morning.

“If you don’t have a tent or a sleeping pad, we can make that happen,” Burrum said. “We’re also working with Green Trails Maps, which is going to provide a little lesson in hiking and orienteering, that is, showing kids how to use a compass if they are lost and how to navigate the woods.”

All families are welcome. The cost is $25 per individual camper, and $20 per camper for groups of six or more. Children under age 4 get in free.

Register online at: http://wrvmuseum.org farm_and_museum_overnights.html. Please check the museum’s website for details. Porta potties will be provided on site. Parking is available in the farm parking lot just north of the entrance.

The setting for all this fun is the best preserved historic subsistence farm in King County and a county landmark with its own listing on the National Register of Historic Places. There’s lots to see, from an 1897 barn, a fully restored 1902 farmhouse, a century-old orchard, three salmon runs in Olson Creek and a remarkable collection of outbuildings, including a smoke house, an outhouse and a weaving house.

The farm, which operates as a living history and environmental learning site, is available for community and special events.
