Travel Logs - Boston

While traveling for business, I always try and have a couple of scanners in the hotel searching out the federal VHF and UHF bands. I collect all the frequencies that show activity in what I call my "Travel Log". I keep logs for all the cites I travel to and then add them to a master database of federal frequencies.

Some frequencies are indentified by listening, some by cross reference from local info and some are just unknown. Here is the log from my most recent visit to the Boston area:
