There's something in the middle of the glass at the very top of this photo, but it's also possible that's something in the tent structure visible through the glass.I've been looking for a latch for the rear window for a while - I'm 99% sure that at this point the Slate has NO LATCH to secure/lock the rear window while on the square SUV. I thought I saw this on a pic from the Sacramento event, but I can't find the pic. There are a number of pics that show the window (in SUV mode) open, hinging on the top, with gas shocks supporting the opened window.
