You can find a lot of the 'old' site if you know where to look... Luckily, most of the older info on the site follows the naming conventions that I used when I ran the website, so I was able to 'backdoor' find points and results archives when I was doing research for Drag Review stories last month. I wish they would've kept everything running while developing the new site(s).
Last update of the directory was in October, so no mention of the Dallas track.

I would've thought that a new track (Dallas) and a new-to-IHRA track (State Capitol) mentioned in the Div. 4 schedule press release would've warranted major stories. Hope Dallas doesn't run into Mansfield-like delays.
