The sky's the limit tomorrow as the T throws open the faregates and lets everybody ride forever 'neath the streets of Boston (well, at least until the end of service), as a way of saying "sorry" for all that unpleasantness back in January and February.
Take that trip to Wonderland you've always wanted to? Family get together at Ruggles? Try to get on and off at every single last stop on the system?
Oh, wait, what, you already had a monthly pass so this makes you no nevermind? Don't be such a grumpypuss. Several local companies and attractions will offer discounts or even free stuff (like a free donut at Dunkin' Donuts) to people who show a CharlieCard or CharlieTicket.
