Our old old GPS has a feature where you can set an "alarm zone" and that
is what I'd use, but your method sounds simpler. One of these days we're
going to update electronics...

On ours (~1992 model) you can do exactly that, it just takes a long time
programming it in. Maybe I'm assuming too much in thinking that other
models have the same feature.
