If you'd like to take a quantum leap in your kendo over the summer, you should consider attending some kendo summer camps, like the one sponsored by the AUSKF in Atlanta. http://www.auskf.org/ When I attend my dojo's weeklong annual kendo camp, I've found that there's usually a noticeable bump-up in my kendo -- after recovering from the grueling training schedule, that is. There's really no substitute for eating, sleeping and walking kendo all the time for a week.
