I've attended nearly every Chestnut Hill Harry Potter Festival and I've got a bottle of Iron Hill Brewery's "Dumbledore's Dubbel" aging at home. Each year has been better than the last, but I think the fest finally reached its true potential last year when they opened up Germantown Avenue to pedestrians. It was a beautiful day and it felt as if every square inch of road was full of costumed fans of all ages. The family activities were fun, if low-budget; the Sorting Hat ceremony and Read-a-thon were my favorites. But, for me, the best part was being around that many fans with ear-to-ear grins just taking it all in.
