64 Detour (Lost Busdriver)

Last Wednesday the 64 bus I was on had to turn right on Parsons street to detour around minor construction near the IHOP at Birmingham Parkway. However, instead of course correcting by turning left at the next available cross street... he kept going...and going.. straight....across Faneuil, across Arlington. I finally roused from my half-awake daze when I realized that he was going all the way up to Washington street, where he FINALLY made a left into tons of traffic.
