As a kid growing up in SE Idaho, sonic booms were pretty much a daily occurrence. This would have been in the mid to late 70's. Some of them might have come from the SR-71...I don't know. It wasn't uncommon to hear a half dozen or more in a day. Mountain Home AFB was pretty close, as was Travis AFB.
I don't think I've heard a sonic boom since I hit puberty, at which point I pretty much quit paying attention. Any idea what happened and why? (Sonic booms, not puberty...)
