I do not enter turns at 180+ mph, however they do not enter turns at 180 + mph at Martinsville either, they are closer to 150. I do approach similar speeds especially at VIR and Road Atlanta.

No offense taken on the comments either. I've quickly realized that this is the wrong place to show things of this nature if I wan't praise. The crowd I run with agrees with it and for the same reasons it was put in place, but thier opinion is still an opinion too.
