Well, you could use rFactor central to find out about different mods and then just do a google search for the name of the team that made the mod. For example, if you were interested in the TPTCC mod, you would search for The Us Pits. And from there, you could download the latest version of the mod. Also, NoGripRacing.com seems to be hosting some interesting stuff. I just got the 1971 F5000 mod and am starting to enjoy it.
Also, fish don't have "relations" in the water. The female lays the eggs and the male comes by later to fertilize them. They just pee and poop there. Hope you feel better about drinking the water!
I appreciate the info about rFactor mods. I have googled for some of them. Really enjoying the NAGT mod. Still use Nascar 2003 for ovals but really needed something for roads, I think rFactor will be it.
Really appreciated the info about the fish, too.
