Hello Kevin,
Just download the kmz from the airspace tab on
http://www.soaringdata.info. The current version is at
http://soaringdata.info/aviation/cou...21.02-25.2.kmz
If you want something for a smaller area, follow the link from the airports tab to the airport query form. Put in a center airport and a radius, and select the checkbox for a companion airspace file in KML format.
