The fun started last week, but there's plenty more on our calendar for Halloween this weekend.
On Saturday, Brookside Nature Center in Wheaton will have a Halloween-themed scavenger hunt on the trail.
Saturday night, take your kids trick-or-treating in Meadowlark Botanical Gardens in Vienna ($10), or to the Halloween party and hike at Potomac Overlook Park in Arlington ($10-15).
Rock Creek Park will show special Halloween-themed shows in the planetarium several times over the weekend. They've also got a program about bats on Saturday at 2:00.
Of course, there's a whole bunch of walks on our calendar that have nothing whatsoever to do with Halloween. Work off all the sugar, escape the sanity on the Mall, or just get out and enjoy this time of year for its own sake.
We'll see you out there!
