No sign at lunch anywhere from Grand Valley Road through to 1st street that I could see. If they're still around, best bet is to go for a drive and follow the river as best you can even going as far as Rec Centre where I caught one on the banks near the new Riverside development. Have a spotter keep an eye toward the top of taller trees near the riverbank (unmistakable big black blob in a bare tree) and up in the air near the river (by far the biggest anything you'll see flying unless the Westjet flight happens to be on the way in
). If they're flying high enough, because of how massive they are you can usually spot them from a fair distance away.
Depending on how committed you are, if you do a Google for what their call sounds like it might come in handy... it's quite distinctive, though with this wind today maybe not as easy to pick up!
