Where are the best public gifted programs?

I grew up in a fantastic program in Renton, WA that has since been gutted. We have two gifted boys and can relocate anywhere in the US, and it's really hard to find aggregate data about where there are high-quality gifted programs (we specifically prefer dedicated gifted classrooms).

Our other criteria is preparing for climate change, so we're not interested in any place too far south. Oregon? Washington? The Great Lakes Region? New England?

We would welcome recommendations of great schools and programs, anywhere, but especially places that won't be too warm in 20-30 years.

Thank you!
