Thanks for all the suggestions guys. I'm ashamed to say that I'd never heard of the kd tree or the quad-tree before. Yes, the current bucket approach works, and yes I'll probably use it this time (Special User Airspace records for display on the kln89 map page), but the possibility of a more elegant approach is something that's been bugging me for a while.
