A Seattle dad’s Halloween attraction that he built in his driveway – Diagon Alley from the Harry Potter series – was wildly popular Tuesday evening, with more than 2,500 people lining up to walk through it.

And at the main entrance, donations poured in from trick-or-treaters for PurpleStride Puget Sound in tribute to Matt Bencke, a local tech entrepreneur who recently died of pancreatic cancer.

The story got media coverage on geekwire.com. The article states that the homeowner, Jon Chambers, and his wife knew Bencke, who passed away on Oct. 19. A “Live for Matt” evening of music honoring him took place in Seattle on Oct. 23.
