I need this PC to show a boston IP address

I need my laptop to appear as a massachusetts/boston IP address. I am from boston but im currently in costa rica... i want to listen to the patriots game but the radio station that broadcasts it online is only accessible to regional listeners. (according to their info page).

I dont know for sure how it works, since this will be the first time i tried listening to it outside boston. But i want to get a workaround figured out before the game starts just in case i have a chance to make it work.

I am wondering if i can get around this with something like TOR browser or something similar... as far as i can tell TOR assigns a random IP but nothing i can choose.

Thanks for any help on this.
