Actually, you may get too much reception
see http://followthatmouse.wordpress.com/tag/dx/ an interesting read on DX and AM radio, one of my hobbies as a youngster.
When stationed in rural NV (Lincoln Co.) I would set my clock radio to KSFO, (SanFran) the signal was that strong in the early morning. Late at nite I could catch the ‘classic radio’ episodes - Green Hornet, SHadow, etc.
Those were the days (Mid 70s)
As long as there are massive segments of the rural countryside seved by AM radio, it will survive.
I grew up DX-ing too. Used to have a whole wall full of QSL cards back in the days AM stations still sent them. In the sixties, I moved from San Francisco to Yuma, Arizona. Man, talk about culture shock! The only thing that kept me alive was that nighttime skywave from KNBR.
