AM, and even FM and PM, are allowed everywhere SSB operation is allowed EXCEPT for the 60-meter band which is USB only.
The only restriction on FM and PM is that the modulation index does not exceed 1 below 29.0 MHz. Glen, K9STH

As to the Window aka 'back of the bus' mentality, that went out years ago.
AM is allowed anywhere SSB is permitted on HF last I knew, and plenty of
folks take advantage of it to avoid the usual congested areas (which also
attract the nut job jammer types). 7.160 was a calling frequency and
watering hole for AM on 40m before the foreign BC stations became a
problem. They're pretty much gone below 7.200 now, but still use the area
between 7.280-7.295 which is probably why you hear less AM there. We've
used 7.220 and other frequencies in the evenings as well.
