I wouldn't judge the premise of the question, myself. Some people enjoy relocating to new areas (and see it as an adventure/fun vs. disruptive) and if you can do that and have one kid and are flexible, then some areas are going to be better fits. Size of area, funding, specific programs, and state+local philosophy on gifted all add together.

We toured the local HG program this week. Discovered the typical class size is around 8, met a number of highly motivated, high energy teachers and administrators. In the process of applying for the HG program, with the testing, the local school TD coordinator on her own initiative got DS7 TD certified. So even if the HG program does not work out we get an IDEP and services for the rest of his school career.
