Saturday we had a lovely day for our basenji clubs, bi-monthly walk in the park. This time was at a scultputure garden in St. Louis. I believe we had 18 basenjis walking ranging in age from 3 months to 14 yrs.
Beaubri Basenji's in mission bc are one of the top basenji breeders in bc if not Canada. If you are still looking I would get in touch with Simone she is the breeder.
I'm not in that exact area but the Basenji Club of Southern Wisconsin(http://www.bcosw.org/) has several activities every year not far from you, one of which is a Fun Day where everyone can bring there dog for fun and games in Rockford, IL. It's on July 11 this year. You should consider joining the club. They haven't updated the calendar on the website yet but if you look in the latest newsletter it has a list of most of the dates for the year. There is also a Chicagoland Basenji Club but I am not as familiar with that one.
