Readme for South Boston lp file fix:

The AI at the converted South Boston track for N2k2 do something odd, right at the start finish line.  They slam on the brakes; the rear end of the AI cars raises up, the nose dives, the whole nine yards.

Well........ da'rock went and made some new lp files that don't slam on the brakes.

He also made a new track.ini file adjusting some of the pertinent parameters like track grip, AI speed, etc.

Enclosed in this zip are the new lp files and a new track.ini.  Just unzip and place them in your SBoston folder.  

You may want to move your original files to a safe place in case you don't like these new files, but I think you will.
