I usually peg the speedometer at 120 on the straightaways and when going up a grade the pedal is to the floor to see how fast I can go before I reach the summit! ;) Seriously though, 65-70 in 80mph traffic is still my comfort zone and I stay to the right. I will pass slower traffic though and will reach speeds of up to 75 to get by (I like to pass quickly, especially if in the oncoming traffic lane.) When it's just little ol' me?... 55-60mph. I like to enjoy the ride when I have time! :)
