If I still lived in Juneau, and had kids approaching high school, I'd move to Anchorage.
My sophomore year at East Anchorage High School we had to double-shift with Dimond High while that school was built. It was a lousy school when they finished it, and this year (after building a beautiful new Dimond high) they tore the old one down for a huge parking lot. They're just finishing a new high school in Eagle River and they also just finished building another big beautiful South High School.
Before this it had been 30 years since Anchorage had built a new high school, Bartlett High. Before that they built Service High after East and the original West High. Oh, and if your kids are still in elementary, well, we have something like 130 elementary schools in the greater Anchorage area, many in the same caliber as Juneau's Riverbend Elementary.
I recently worked a long-term sub job at the new Dimond High, and I have to say it was a wonderful experience. The kids seem to be in awe of their surroundings, and although I had a few who liked to do what high school kids like to do to substitute teachers, they knew what they were there for - and why the public supported such a grand monument. It was easy to point out the obvious.
You won't find that in backwater Juneau.
