A couple of years ago, I suddenly got interested in watching different kinds of sports(Before that, I only cared about basketball)...There's something about people competing against each other that intrigues me.....Anyway, I was browsing channels and I saw these open wheel cars going at 300+ KPH. I couldn't take my eyes off the TV set and the rest is history...Right now, F1 is #2 in my favorite sports list...I'm planning on going to Singapore this year to watch my 1st live F1 race(This is the easiest place to go to since there's no VISA requirement for countries that are members of the association of southeast asian countries).
Go for it!!! You never forget your first live Grand Prix..... Mine was Melbourne 1996.
I still remember the hairs on my neck standing up when I heard the magic piercing sound of a V10 come past on full song!!!

If you can afford it, do it in style, with the best tickets you can afford, and try to get an event (dinner) etc where some drivers are present, or a pit lane/ pit straight walk, if they offer them....
Once out there, be sure to walk around the track, to see them belting through the CORNERS, not just straights.
By the way, those pics are at the last chicane at Imola, the downforce settings on the cars give it away.....
Singapore looks like an awesome venue to be at too....
