Wow, that sounds like it was a nasty incident. Always nice to hear of full, to nearly full, recovery stories.
Finances really aren't in my play for 2013, to do Endurance, but your offer is appreciated.
There are some other guys on here in the market for doing Endurance. There are two other Dallas-area forums that you can hop on, and get more information for those folks.
Most of the real track day guys are on MotoDFW.com; which is a Ride Smart track day owned forum. So, there's no talk of other track day organizations there. ...Not even the open ECR days.
I don't participate with that track day organization any longer, and am actually banned from the website too (others on here can vouch for what happened, but it comes down to the fact that some of their past Instructor's were super-a-holes, and I got fed-up with their attitudes, and shyt talk, when I was faster then them after / about one year of riding).
I do know that there is a guy on there named Jack (Moss last name, I believe), that is getting an Endurance team together for 2013.
The other site is DFWsportbikes.org; it's not a very active site, but there's some decent folks there. They mostly only post up about Ride Smart track days, and the ECR days, but not too many other type of track events.
If we get an ECR open day planned, we'll most-likely have it posted up here!
