Details about my leg: We'll be flying a Cessna 172, tail number N53491. Ground speed is about 100kts. We won't be going direct, seeing as how that would put us way out over the lake and in Canadian airspace, so the route will look more like KCGF SKY KBTL. The AOPA RTFP puts it at 1.75 hrs, plus your .5 ground time gives 2.25 hrs. That also puts distance at an even 180nm. I am not instrument rated. Bob Ciotti, look for a PM with my cell number and a few details in it.
