I would imagine the yellow lot is the easiest and cheapest option....But building the field house in a prime lot where many donor may not help create more donors. The catty weirdo may disagree, but those are conversations that have been had by many yellow lot pass holders. There are other options, but for some reason, they are choosing the Yellow lot option.
Personally with the field house and lacrosse field on the blue lot parking nearby will be hard to get and thats under the assumption the bubble will stay for other sports. (sorry i dont think RU will take over part of the golf course)
RU will build on cheap, instead of putting the field house on the brown lot and tennis courts and building a parking deck on the white lot...
