Wake up. Put the dog in the car. Better if there's more than one and they're Labrador retrievers. Head out to Verrill Farms as early as possible for their incredible scones. If you get there early enough, they'll still be warm. Dare you to walk out of there with just one. The quality of the coffee doesn't match the scones, but it'll do. Then hop back in the car and head east on Route 117. In less than a mile you'll see the small, unpaved and unmarked parking lot for Mt. Misery on the left. Pull in, open the car doors, and smile as the dogs tumble out of the car in excitement. The main trails require that dogs be leashed, but as far as I can tell it's not enforced. Explore for an hour. It's small enough that it's hard to get lost. Enjoy the magnificent scones you just bought, the astoundingly beautiful trails, and the pure joy of the dogs. Make sure you have towels with you; I find that even the most obedient lab can't resist the temptation of the Sudbury River.
The leftover scones will be fine the next day, but not nearly as good as the day you got them.
