We had a tight schedule to our trip Niagara Falls-Boston-NY- DC. First we started from Niagara Falls, could not go to Canadian side, we missed the true beauty of Niagara Falls (as every one saying that it looks more beautiful from Canadian side).  Saturday afternoon we arrived to Boston, all of sudden our car started showing its trouble sign. Check with auto parts store, it was the ball joint need to replace. All mechanical stores were closed in the evening we had to be in NY on Next day to be on our schedule.  Luckily the host browses on internet and makes some phone call. About an hour the walking garage was in the yard. About 2 hours he was struggling with the the ball joint and we were enjoying the chilled beer. Thanks the Bostonian friend for helping us with the walking garage and saving our two days (need to wait until Sunday to open garage). He did not only saved our time but the repair cost too (total $85 labor and parts). Thanks to Aaron the mechanic (mechanic’s phone 508-335-7088 in case you are interested) and Bostonian friend. We missed the Bostonian's Monday Party but we were saved this way.
