Hi Justin,
<Billings is one airport that really does sit on a plateau, so "fixing" it, <has actually borked it.
Agree it looks kind of ugly, and any "magic" you can perform to massage it into shape will be greatly appreciated.
Off the top of my head, other actual "plateau airports " that may require similar treatment are KSEZ Sedona AZ, KABQ Albuquerque NM, KCRQ Carlsbad CA, KHIF Hill AFB UT, KSGU St George UT, KTEX Telluride CO, KASE Aspen CO, KAVX Avalon CA, KMSP Minneapolis-St Paul MN, and KCRW Charleston WV
Many thanks,
Lee
