Should you be traveling through Kingston ON,I would recommend visiting Fort Henry and attend the evening military performance. The guide tours are interesting and in formative. Also, visited the prison museum, via the hop-on hop-off trolley tour. Kingston also has many interesting pubs and restaurants to tempt your taste buds.
Glad you enjoyed visiting Kingston. I've lived here all my life. Fort Henry is a very interesting place and there are a number of things to see and do as well. Some I have never checked out even though I've lived here for 49 years.
