Snowball fight and sledding!
I had an amazing time when we snuck off to the snow bowl to throw snowballs and inner tube down the hills a bit more than a year ago, and want to go play in the snow again.
After the meet (we want to be out well before dark) we can head back toward North Bend and warm up for dinner.
The Hyak Sno Park is across the interstate from the Gold Creek trail area, Exit 54, and both locations are well-marked with signs. A snow pass is required, but cheap and available online.

Carpooling is recommended, since we pay per car to park.

It's still (sadly, thankfully, whichever you like) much cheaper than the $20 per person for 2 hours tubing over at the resort :)
