Took off from orlando ex. in a 172sp into a strong cold front, headed to jackson Miss. It took 7.6 hrs. With 2 fuel stops. The next day we took off and climbed to 12k and had a g/s of between 189-193 until kocf when we had to start our desent back into orlando. it took 3.9hrs with no fuel stops. I did the flight plan before hand and checked the winds aloft, but honestly did not believe what they were saying!! WX is quite an amazing thing....
