I got stopped for a 149 in a 45 once but it was my dad's best friend and he just chewed me out and wanted to check out what I had under the hood of my Camero!!! I also passed my Dad on my GSX-R750 once, he was doing 75 and said I shot by like a bullet. I know when I had it flat out the speedo would read 180 but I think it was off a little...not that it mattered!!!
I still think Mile high is the over all hardest to get. There are some that are very time consuming and some that are hard but if you play enough you can get lucky.
Your never going to get mile High with Luck!!!
I still maintain that the last one from Hexic HD is the toughest!
You can't get that with luck either. I'm NOT, NOT, NOT saying MHC is not an extremely difficult achievement to get, but there is a pattern that can be memorized which makes it more of a grind than anything in my opinion.
Flame me all you want, I'm a big boy! I can take it!
I'm also biased because the Hexic achievement is MY personal most difficult that I have unlocked!!
