Well, to be fair, my "outs" would have been to either hold at HGR until
the storms fizzled out, or to land back at KHGR and wait it out on the
ground. So, no, I wasn't really in an emergency, just in an awkward
position, especially without access to real-time weather in the
cockpit. Plan B would have been to call flight service from the hold
and see what their radar was showing. What puzzled me was why I got the
clearance in the first place if it wasn't going to be honored. Of
course, in a few weeks, when the GPSMAP-396 arrives, none of this will
be an issue anymore...
