Hi Jim
Congratulations on your effort.
Have you ever thought about dropping down under? We have a great little track in country NSW called Mount Panorama, they have a 12 hour race in early Febuary each year with an invitational class that would suit the P4/5 down to the ground.
As a bonus you get away from the northern winter, I am sure we would be able to round up some help if you needed people on the ground.
