We're 2 couples, mid 60's, planning to check out sites along the Erie Canal on our drive from Boston to Niagara in late June. We'd like to take 2 or 3 days. We like easy hikes, cycling, history, scenery, and want to go thru a lock or 2 on the canal. Suggestions please-there is much to chose from. Not interested in shopping or wineries. One of us is a big train fan-any in the area? Thanks.
