I live in Boston and literally just spend the better part of my day trying to make a donation. I packed everything up and dragged my stuff downstairs to the concierge desk in my building, walked 15 minutes to my parking garage to get my car, drove back to my building on a busy street and double parked to quickly load up the trunk. Then I drove what should have been a 10 minute drive to the Kenmore Square Goodwill but turned into a solid 30 min because of all the traffic from BU's graduation ceremony. When I got there, all the parking spots were blocked off and police were forcing traffic to keep flowing. I went around the block several times looking for parking before deciding it was pointless. I quickly Googled the next closest Goodwill store, which is in Jamica Plain, and decided to go there instead. There's no graduation in Jamaica Plain today but the Goodwill store there is also on the main road with very little parking...
You can always donate to Boomerangs with a little more ease. They're a few buildings away from the Goodwill on Centre and you can pull into their back parking lot while you are dropping off. Cool store, too.
