There's one repeater on 29.620 MHz I believe...and I think it's in New York or the northeast USA anyway...during one of the bigger band openings we've had in the past weeks I heard traffic on 29.620 FM as well as 29.600 FM simplex.
Also when the band is opening there's the land mobile users on 29.710 MHz FM, 29.730 MHz FM, 29.750 MHz FM, 29.770 MHz FM and 29.790 MHz FM. I know there are car service dispatchers and taxi dispatchers in New York City on 29.770 and 29.790...plus school buses and rideshare buses on 29.79 MHz or 29.77 MHz. There are several other users of the 29.710, 29.730, and 29.750 frequencies in that part of the country. If you can hear those repeaters, you can hear the land mobile systems on 29.71-29.79
