Well, I started to read and wanted to comment but my memory sucks so please forgive me if I forget names.
The race track: EXCELLENT. At first I thought it was strictly for drag races but then I saw the track did actually make a loop. Well done. What size lot is it on? I'd like to see one on a huge lot to give that "Daytona" appeal to it, or Grand Prix.
Actually it was just supposed to be for drag races, and then I realized the entrance, exit, and pit road all made it look like an oval track. I have redone it now and I think its shaping up better to what I had envisioned. It's on a 64x64 lot. Unfortunately I cannot make the track to scale, as an 1/8th mile drag strip would be too long for a 64x64 lot. So its more like a 1/16th mile racetrack.
I do plan on making a Daytona style track, I just have to play around with making the banked corners look right.
Also, I have figured out that you cannot place vehicles on a community lot, so it will now be a really cool home lot, as I don't feel it looks right without any cars on the track. I can make use of the race car bed I have now.
Here is the new racetrack. Also in case anyone it unfamiliar with what a Drag strip is, here is a picture of a real one.
