Asphalt is excellent, only a few bumps where pit lane joins the track. True run off is lacking (similar to Summit) but almost every turn is very wide so if you have a bobble there is plenty of track to gather it up and keep going.
There is no chance to catch your breath, even the straight has a few hairy bits (the aforementioned pit out dips will produce some good wheelies at WOT before shooting up the hill) so concentration is taxed. I find myself cutting sessions early if I have one brain fade moment, pit in, rehydrate and get ready for the next session.
A different experience to a full fledge track with fat curbs, run off, ARMCO(!!!), but a great place to improve your riding and the owner Greg along with his staff are excellent hosts. Very laid back as long as you are not a jackass.
I prefer when they run the clockwise Downtown configuration since the majority of the turns are now uphill which increases confidence. The Uptown configuration has me worried about low sides all the time but you do get to tackle "
wheelie hill" turn 7 in that configuration. Get it right and its a real thriller!
