This question is almost as common as “when’s the best time to go fishing” and is more about perspective.
Most outfitters market themselves as “Fly-In” meaning you have to fly into their location(s). KaBeeLo’s perspective is that once you get to KaBeeLo, we fly you OUT to your remote OUTPOST. Hence “FLY-OUT”. It’s that simple!
Maybe the term “Drive-In; Fly-Out” makes more sense?
