You’re spot on!
This is almost right at the border (you can see the Queenston / Lewiston bridge in that pic above.)
It’s like 10 minutes from where the Niagara meet is held every year.
I know I’ll be seeing some of you guys there 
EDIT: And you don’t HAVE to register to show up since this is a free event, but we’d appreciate if you took the time to do so. We’d like to have a close-to-accurate number of cars. We’re expecting 100+ as it is!
