rarely driven car - oil change in Spring or Fall?

I like the suggestion to take a long drive to evaporate any moisture in engine/oil before storage. I also like the comment about using your eyes to help make the determination about changing the oil, because like the oil degradation link posted, confirmed that that can be a viable evaluation, in lieu of oil analysis.
Something that is mentioned on other forums, is that with extended oil change intervals (time and/or mileage) there comes a point of paper filter media degradation in oil filters. That's why some are recommending synthetic filter media oil filters. For example, Wix 51515xp, instead of the tried and true Wix 51515.
