Congratulations! Diva and I track too. I'll probably get her certified later this winter...she's not quite ready but should be soon.
One of my go-to places to track right now is an empty lot in the middle of an industrial park near me. Because of a recent ankle injury, though, I've needed to avoid uneven ground, so we did some shorter motivational tracks on the lawn that abuts that empty field...it belongs to a local uniform supply company. One day the plant manager comes out to ask what I'm doing.... I answer training my dog to track... he asks if that is like Search and Rescue... I say....sort of the basic building blocks.... he says fine, I can use the property any time I want. I suppose I need to send a tray of cookies to that company's break room when she gets her TD ;)
