We had hoped to take a long road trip starting in mid-August, but now it looks like we will have to wait until mid to late September to start, or possibly put it off until Spring. I;m wondering about RV parks closing for the season and wonder when they starts to happen. Our trip would take us through lower Canada and upper New England before returning to the Midwest. Any advice? We have a smallish travel trailer which has a furnace for heat but unheated holding tanks.
