Feature request: limit area of geo-location search (remove "Any" option)

I would like to be able to remove the "Any" option for the distance (5,10,25,100,Any) when doing a geo-location search, or alternately define a max radius. In general we don't want people to do be able to do that. (As a comparison, other location services like storepoint.co and zenlocator seem to build in this limit).


Thanks

Out west, there are times when the search result is greater than 100 miles away so I vote leave "any" in.
