Jerry,
I completed the Forest Experience Rally school one day course back in 1997 while living in England.
The setting in Carno and Caersws (sp?) Wales is absolutely beautiful, plus Tony and Christina Higgins were really nice and took care of getting me from the train station and back to it.
On to the content here... The school was great, however I could only afford the class where you share a car with other drivers. We all shared the attention of one instructor (David) for the day. I drove the Astra and kept having trouble with sitting on the right side of the car (even though I'd been driving right handed cars for many months) and with the rock solid brake pedal.
The only drills we did were around a logging lot where we practiced handbrake turns and slowing down enough for tight corners. Most of the school was blasting down some great logging roads around the course.
Truly a top notch school- perhaps get a little experience first so you can really learn what there is to be learned.
I haven't been to Tim's school yet, I'm waiting to go after it feels like I can't learn from myself anymore. I've heard great things about Tim's courses and if you consider a cost/seat time comparisson I believe you could get a lot more seat time up in Vermont without flying to the UK and getting yourself to Wales.
If you've never driven aggressively before, do some autocrossing or rally crossing to be comfortable with sliding the car and pushing it hard first. If you're not yet settled in with throwing a car around the course may not be as beneficial.
