Bauman's Harvest Festival Remind Like List
Among the various activities at Bauman's annual harvest festival, you can find your way through winding mazes, shoot some apples through a cannon and watch them explode, or slide down a giant hay pyramid. If enjoying apple season is your main objective, indulge in seasonal treats like Bauman's famous apple cider donuts and sample some fresh-pressed cider (weekends only). On October 6, the farm will have its annual giant pumpkin weigh-off, followed by a 1,000+ lb pumpkin drop from a crane into a pool of water. Cannonball!

The MAiZE at the Pumpkin Patch Remind Like List
The famous MAiZE on Sauvie Island is back this year with an absolutely adorable Peanuts design—an homage to the Great Pumpkin, I suspect. Peanuts is celebrating its 75th anniversary with a year of activations like this one around the world, giving local businesses the opportunity to finish the statement "Happiness is..." (in this instance, a corn maze). The maze has two parts: warm up with the "easy" section before tackling the more difficult part, and don't forget your boots—it can get muddy out there.

Plumper Pumpkin Patch Fall Festival Like List
