IMO Nelson is the friendliest “big track” (4th~5th gear) around. What is it? Turn 6 @ Beaver is blind as you are cresting.
The price is cheaper @ $120, and is actually closer than Beaver (by 15 miles). The advantage to Beaver is that there are always instructors/trackies hanging around (then again it was a weekend vs. a Friday). I was instructed by a guy that “just showed up because he got a call”.
