Losing the Mine Train rockwork + Big Thunder Ranch for long, empty walkways to Galaxy's Edge was already a blow. Such an underutilized waste of space in a park that really doesn't have long, empty walkways.
Losing the last bit would be sad, and it would also impact the Rivers which already don't feel as secluded as they used to after being shortened.
Exactly and what could they even put that there that would be worth it?
