What's left in the season - MW or SE?

Seems now that my teammate and crew are all burnin' to get some enduro time in, before the end of the season if they can swing it. What's left as options?

What I know of:
Last Chance at the Glen - complaints are that it's too far of a tow for such a short enduro (3 hrs right?)
Charge of the Headlight Brigade - complaint is mine, 13hrs is a long race to cut your enduro teeth on IMO!
ARRC enduro - as with the Glen, helluva long tow for just the enduro; if he gets convinced to run the ARRC, that helps the equation
NASA RA enduro in Dec - NASA, no good class to run, doesn't have a HANS, isn't a NASA member, no real plans to join

What other options are out there? We're in Detroit, so NE/Midwest/Atlantic Coast tend to be preferable...

Midwest Council runs 'That Long Race' at Blackhawk Farms each fall. It is a 100 lap race (typical regional club races are 18-22 laps). They do run IT classes.
