An international gathering of Citroens occurs on June 13- 15 in Ballaston Lake/Saratoga Springs, NY. The best day is on Saturday the 14th for the show and BBQ.
I'll be taking my 1969 DS... however there isn't room for additional occupants this time.
If it's the kind of thing you like, I hope to see you there.
Also be sure to check out the Saratoga Auto museum.
