New Hampshire Fish and Game officials say they are in peak foliage season and visitors should expect crowds everywhere - from parking lots to highways to trails.
Be prepared for traffic
Colonel Kevin Jordan of New Hampshire Fish and Game said people should prepare for stop-and-go traffic as people flock to the area, with the northern routes being especially heavy on Fridays and the southern routes seeing congestion on Sundays.
He also warned drivers to be careful about pulling over to get that perfect foliage picture, which has caused accidents in the past.
