I just remembered there was something interesting about it. Here it is:
The location, in a former indoor party area next to the main entry gate in center field, will not be accessible from within the ballpark on game days, a restriction mandated by MLB. The Nationals will share in revenue from the sportsbook, calculated based on handle.
Along with the retail outlet, BetMGM gets access to operate its mobile app within two blocks of the ballpark, a radius that includes the riverside restaurants and bars of DCâs white-hot Navy Yards neighborhood. DC sports betting regulations only allow sportsbooks to offer mobile betting within that distance of the districtâs major sports venues, which sub-license those rights. The DC Lottery is the exclusive operator of mobile betting outside those carve-outs.

Betting is run by the lottery in Oregon too, and unfortunately the legislature here is still pollyannaish about college sports (Oregon used to actually have an actually sports betting lottery ticket, which they got rid of in order to host NCAA basketball games).
If I wanted to bet on college football - and it's probably just as well I can't because following a sport closely doesn't necessarily make you a better gambler, especially when entertainment and sentiment enter in - I'd have to drive to reservation land, where I could then use the MGM app, or go into the casino.
