Hi Bob,
I have also played there about 5 times, as we have a family house on a lake about 50 miles south, and we have explored most of the area courses over the years.
AVCC is a good golf course, one might even say very good especially considering the region. Presque Isle CC nearby is also pretty good, especially so for the northwoods. It sits on a long narrow property right against the border on the Canadian side (all holes are in Canada), with the parking lot and pro shop on the American side. Arnold Palmer famously visited in the 60s. Conditions are normally good, and it has the feel of an old course with upgrades made over the years that maybe removed some character but increased fairness.
The membership has dealt with alot over the last few decades, as nearby Limestone AFB closed in the 90s, taking with it a good portion of the local population and many jobs, and inevitably hurting the # of prospective members. Border reviews around 2005-2010 identified the course property as a "border weakness," and required Canadian members to head to town to the border crossing to check in before coming back to the course, even if they lived next door. COVID-19 has certainly complicated things, as the Canadian members seem to be shut out by the quarantine rules.
I think as a Mass. resident I'm supposed to quarantine for 14 days in Maine if I want to play golf there anyways, so I guess it's not too much different at present.
