Best time of year to visit back east / north?
Hello, this if my first visit to this forum!
We are planning a road trip around the U.S. next year. We'll drive across the south through Texas to Florida, up the eastern coast to the northeast (probably as far as Maine), then back across the midwest through Ohio and Illinois, probably up to Montana, down through Wyoming, Colorado, and back home to southern California. We plan to take about a month to make the trip.
We're planning to take the trip in the spring or early summer next year, and we're wondering which months are best in terms of weather. Would May/June be the best time overall? We'd prefer to avoid the south during the hotter months due to the humidity, but we don't want to get caught in unexpected snow in the north in spring either.
What do you suggest?
