I was in ANC in the first day of May around some 4-5 years ago or so. Beautiful state indeed, far to get to. Around 8 hrs from IAH. But alot closer than NRT or MNL. It was cool that time of year, but not brutal. When we were driving to KENAI peninsula, up in elevation it was snowing. I pulled the car over so my wife could see how it looks when it snows, though it wasn't heavy snow, it was good enough. Wife being from tropics, she got to see it snow a little in Alaska. Driving to Seward, also, snow along the Russian river, and still somewhat icy. White all on the ground. In anchorage, it was all cold rain. Porter Glacier near anchorage in itself is a beautiful drive and the glacier feels like you're standing in an ice box. I tried hitting Gwenies, but it was closed. I'd say go now before the kids get out of school, avoid the summer rush.
