I've lost count of how many times I've been through Singapore now on the way to various places. But when I took a 2 month trip to Indonesia, the 2008 Formula 1 Grand Prix here (the first night race) fitted in very nicely between having to leave and re-enter Indonesia on a visa run.
I've been to a few Grand Prix's now, but being part of the night race was something else! We were able to get right up to the edge of the track, being so much closer to the cars as they roared past - the amazing engine notes as they fly past - no ear plugs for me!
