The 'official' three tram stops at that back end behind Homebuilts are across from the North 40 Red One Market, the Homebuilt pylon by their showers and lastly at the Vendor's Parking lot - Uber/Lyft stop -Nature Center pylon.
I can't answer why the pylon is not by that entrance gate rather than the HB showers? I did often stop the tram at that gate to let folks board, but technically that is a violation of tram operating guidelines. This was just the 3rd? year we even ran the Red route back there in no-man's land - lol. You'll recall we used to always just loop around at the North 40 gate and come back to Warbirds and the forums. In truth this year, at least on my tram runs, we rarely picked up more than a handful of folks total for those three stops on the West end, so I don't know if it's worth all the time it takes for the very few riders it carries. But hey, I'm just the guy who gets dragged wherever that John Deere up front takes me - lol
