Norad45,

I'd be glad to. I live in Bellevue, Nebraska (in Sarpy county), just South of Omaha, Nebraska (in Douglas county). In the metropolitan area the transition from city to city and county to county is seamless. If you don't know which streets are the boundary line you'd have little way of knowing which county you are in.

The cellular telephone network for the metro area doesn't distinguish between the two counties, at least it didn't a few years ago, that may have (probably has) changed. In any event, in my limited experience all calls to 911 were routed to the Douglas county 911 center. If I wanted to report a problem in Sarpy county they had to forward my call. I learned (very quickly) that if I called 911 from a cell phone that I should ask for the 911 center which served my location.

I first ran into that problem on a cross country trip about 15 years ago. I was driving across eastern Iowa, near the Illinois border. I called 911 to report a traffic hazard and the call was answered at an Illinois 911 center, they explained that I needed an Iowa office and transferred my call to the correct center. I got the impression it was a common occurence.

I suspect its more of a problem in 'border' areas. It's likely that the cellular system is better equipped to route calls to the proper center based on the location of the servicing cell tower than it used to be. But when I can drive North from Bellevue, Nebraska (Sarpy cty) through Omaha, Nebraksa (Douglas cty) and over the Missouri river into Council Bluffs Iowa (Pottawatamie cty) in the span of 10-15 minutes I'm not sure the cellular system will ever be capable of providing total coveragle (no blackout areas) as well as 100% accuracy in determining which 911 center should be servicing my call.
