Haskell Free Library and Opera House sits on the US/Canada border. Two front doors, one building, a thick black line drawn diagonally across the floor.
The map gives it one address. Ask by name from either country and it answers 93 Caswell Ave, Derby Line, VT 05830, USA. The Quebec door isn't in it. Stand on the point and reverse it, and the seam shows: "93 Caswell Ave, Derby Line, VT 05830, Canada." Vermont, in Canada.
The only camera the record puts on that spot is inside, on the opera house stage, in the Canadian half. No photo of the street. Last look it has of the place: June 2017.
Dated field note, walked 16 Oct 2026.
