I'm against trail closures based on the calendar only because there can be conditions/places in the winter and spring during which no trail damage is done from riding. With sub freezing temperatures, preferably on overcast days (or early in the morning), I've been able to get out on a number of rides this year without doing any trail damage. At times, my investment in studded tires has made what otherwise may have been dangerous conditions completely rideable. I know that this doesn't address the poor judgment used by some during this time of the year, but I'd like trail closures, if needed, to be based on actual conditions. Maybe that becomes too complicated a call. The longterm weather forecasts make the foreseeable future look challenging, but I'd hate to see "the baby thrown out with the bath water."
