It’s October, which means visitors are descending on Valley View Farms to see this year’s giant pumpkin.

The Cockeysville garden center is hosting gatherings in its pumpkin patch all month long, encouraging folks to guess how many seeds are in the largest oblong orb.

You can head up to Hunt Valley to venture a guess, or check out the other Baltimore County events we’ve curated below.

Debunking historic myths

Texas Quarry tour

10-11:30 a.m. Monday

Ever wonder who built the Washington Monument in D.C.? Maybe you’ve admired the portico and spires at St. Patrick’s Cathedral during a trip to New York City.

Register for a tour with the Historical Society of Baltimore County and join for the views at 430 West Padonia Rd. in Timonium. It’s free, but registration is required and space is limited.
