Avoiding caravans is not difficult. Stay away from FHU CGs. Seems most caravan people cannot go without all of the conveniences of home. Avoid travel at the peak caravan activity time. Go ahead of the wave or follow behind.
In 3 Alaska trips we have only shared a CG with a caravan a very few times. Watched one pull into Palmer for a 4th of July. Amusing to watch as they all pulled in, set up their flags, banners, all the usual 'stuff' that gets put out, wandered into the conference hall for the days debriefing, then disappeared to dinner somewhere. By 9:00 the next morning they were all gone. Rushed off to the next stop who knows where.
