Once you move that far (1500 mi) you should be fairly safe, provided you dont make contact with JW in your new location. That is pretty far, for even the most persistant of elders.
Contrary to a lot of opinion, most elders are too busy with there own life or with the JWs who do show up to put forth the effort for anybody not in the territory, much less out of state. The rest are much too lazy. And I know of no elder who would go searching on the internet for any individual jw. Dont worry...you should be ok. Just try not to make contact with the locals in the new area.
