I have never been to the Trinity Site but if you want a chance at catching a live fire at a bombing range, check out this: http://maps.google.com/?ie=UTF8&z=13...60675&t=k&om=1

It's off US84 outside of Clovis, NM and I have caught many a B-1 and B-52 runs. You have to drive on some off the beaten path type roads and I definitely suggest a truck.
