Also in the vein of 'trying to force these clues into cities we think are likely'
Looking for 'The Swallow'. In Spanish swallow is Golondrinas.
There's a ranch Ranco de las Golondrinas that outside Mexico City, and the famous basejumping caves the 'Caves of Swallows' farther still outside the city. Neither of these are in the city though, so I'd call them low chances.
In French Swallow is Hirondelle.
Paris has a Bike Shop called L'Hirondelle Bike Shop . Paris also has a street named Rue d'Hirondelle and yes, another Massage parlor called 'petitehirondelle'. I'm not making this stuff up. Maybe Fletcher is a bit of a freak?
There's a town called Hirondfelle somewhere in Quebec province.
In Montreal there's a Social service center called L'Hirondelle Service d'Accuiel. I think it's kind of like a hostel?
Also there's a Park called Parc de Hirondelles in Montreal.
In Saint Petersburg/Moscow...I'll be honest trying to read maps in Russian makes my head hurt. I don't see anything obvious though.
Anyone feel strongly about any of these?
