Well, I found one problem with the Barber track. It's woefully underrepresented in the racing video game world! (This is true of most US tracks, unfortunately. It's rare to see even top tracks like Watkins Glen or Sebring.) As far as I can tell, no game comes with it built-in. I wanted to do some virtual practice before driving it for real, so I went on the hunt.
My first find was that iRacing has an official representation of Barber. I found a free 3-month membership I picked up at an IMSA race last year and signed up... only to find that the basic membership only gives you a small handful of tracks, you need to buy
each extra track. Barber is $12 - on top of the monthly subscription... yeah, I don't think so. From what I can see, iRacing only makes sense if you don't mind spending a lot (LOT) of money and mostly care about racing online - which I couldn't care less about. No sale.
I dug some more and lo and behold, I find that someone manually built the track as an add-on for rFactor several years ago, and that's been adapted to a few other games (GT Legends, GTR2, Race07, rFactor 2, etc) - I already have several of those in Steam, so I quickly installed GTR2, added the track, and there it is - a pretty decent representation of the track. I did a few laps with a gamepad and will try it with the proper steering wheel tomorrow and start getting some laps in.
If you go looking, the trick is that it's often listed as "Birmingham", not Barber. I found the downloads at a forum called NoGripRacing - you need to register but it's all free. While you're there, you can pick up the Lotus test track in Hethel, too!
In the "real" world, my Elise exhaust just got welded up today - no more squeaky Larini until its warms up - then the HIDs go in and the new steering rack gets installed, then it should be all set for the trip and I can focus on the Elan!
