Today, 3431 made an appearance on route 59, block 2001. This is basically unheard of because the Neos are banned from weekend service. The reason why the bus was in service today was because members of the Motor Bus Society were riding the system. Later that day, they were transported to the meeting in 4 Southen buses, and rode the sytem a little bit more after the meeting. Many thanks to TransitchuckG for this information.
