I haven’t played there but I had a similar experience at The Ole Miss University course. Carts would shut down if you got too close to the green but there was no signs indicating where that line was. The distance varied from hole to hole.Have you ever played Perdido Bay? There is a hole on that course that’s on my list because it has GPS carts and when it’s cart path only the cart will inevitably shut down because you have to cross the fairway to go from one path to the next.
