Yeah, I hear you. We love the Les Cheneaux but haven't yet gotten to the North Channel. Circumnavigating Superior is definitely on the agenda.
The Admiral is creating pottery as her
retirement avocation, so she wants to be near the tourists to peddle her art. And I don't expect to fully retire, which necessitates a useful
airport in reasonable proximity (e.g., TC).
Frankfort appears to be an available & affordable alternative, though bay sailing when the Big Lake is too rough doesn't happen. OTOH, it's a reasonable crossing to Door County and Green Bay, plus the Bays de Noc. Cheboygan might be an option, but Alpena & Rogers City are likely too far off from the tourist traffic. And the air
service issue.
