dmey, there's got to be a way to network amongst other Basenji owners on the island and see if you can form a meetup group! Local dog shows? Postings at local dog parks? Community online message boards?
I definitely feel lucky (and spoiled) to have so many wonderful dog parks in the area. I have the choice of… at least a dozen off-leash dog parks within a 30 minute driving range. And that's only counting the ones that we've been to! At least four of them are as gorgeous as this one, overlooking the Bay.
Driving in my city today, I spotted yet ANOTHER basenji that was not at the meetup and whom I've never seen before. Would've pulled up to say hi to her person if they weren't walking alongside a busy street...
