Was just relooking @ GSV for fun here again to see if by some odd chance they'd updated showing the numbers (since the exit updates were pushed today), but no luck yet.
HOWEVER, the day they traveled thru there back in Sep '23, was the exact day they were putting up the Gore sign for the exit and I didn't think to zoom in @ the truck there. Low and behold, there's the exit number still uncovered. HAHA!
