Most memorable cameo of 2009: SBS 9889U - Service
99 (20 Jun)
3rd last trip: Close to 20 bus enthusiasts catching it. Most
stood on road divider along Commonwealth Ave West outside
Clementi Interchange to photograph before dashing across the road
to take the bus. On board the bus at the same stop, one bus
enthusiast tried to photograph the photographers in action - the
photo showed one photographer blocking a BC. Some took their
photos at Jurong West - the bus enthusiasts on board were captured
making monkey faces on camera. 
2nd last trip: About 10 odd bus enthusiasts (including
me) stood near the junction of Commonwealth Ave West and
Clementi Ave 6 to take photo. I took the next bus (SBS 2610C) and
went all the way to Jurong West before crossing the road
at Boon Lay Ave and taking SBS 9889U all the way back to
Clementi. At Clementi, some stood at the junction of Commonwealth
Ave West and Clementi Ave 3 to take photo. The bus bunched with SBS
8071T from Jurong East Ave 1 all the way to Clementi, but the
"race" was eventually won by SBS 9889U, who came in front of SBS
8071T.
Last Trip: Only one bus enthusiast went to catch the bus on it's
final 1734 hrs trip. The bus went off service after 1926
hrs.
