I was leaving Willis, near Conroe, after a visit with my brother and had stopped at a new Exxon station on FM 830, west of I-45. This was about 5:30 this evening (Saturday). I was filling up my GN and looked up and there was a super clean GN (could have been a T-Type) passing by, headed west. Sounded nasty. Anyone on this board? Sure was a nice ride. Wish I could have met the driver.
