As a fan, I always hated it. So far away from the field and the stands always half empty because they are so large.

Main reason why I love Mt Carmels set up so much - such an intimate setting being so close to the action.
All the blue (bleachers and track) is an odd choice for a community field that clashes for JCA and St Francis.
I think the vast seating and areas around the field for standing room viewing were previously features that have only become bugs in the last 10-15 years, so the time is right to make the switch now for sure. For decades until the mid 2000s, a lighly attended game would have 3-4k in attendance and 1-2 games a year would be capable of having over 10,000. The size of the stadium was needed for that and it made for a great environment for games against MC, Morris, Providence, Marian, the Brook, NN, etc.
Now we are in an age where a lightly attended game may have a few thousand if lucky and even the biggest playoff games may be only in the 7k range, that size and scope of the stadium which was previously needed and made for a great environment now detracts from the environment for 90 percent of games because of how cavernous the stadium is.
In the last 15 years, I can only think of the following games that were packed on both sides.....2012 Montini semi and the 2023 PC semi and even those "full" games were still south of 8000 in attendance.
The 2024 Morris semi and pretty much any regular season Providence game seemed to be "half" full at maybe 5k or a shade over that.
So in 15 years, I can think of 2 "packed" environments and even they were probably in the 7500 range, not 10-12k.
From 1980-2007ish, that number of games over 7500 in attendance would be at least 2 per year and often more than that. Memorial was great and served its purpose. Just like MC discovered with Gately, the era is different now and accommodating crowds of 12,000 is likely a thing of the past. So the time is right.
