"Not as late as last year", I answer.
Last year, we departed around November 1st, and see what we encountered in the Blue Mountains of eastern Oregon. (That doesn't look like "endless summer" to me). We crawled along at 15 mph behind a snowplow for many miles up and over the summit. So, we contemplate an earlier departure this year, not so much to avoid snow (that's actually rare), but because our internet contract expires on Oct 9, and OH MY GOD!!!! How on earth would I get by, I ask?
