I've heard that one of my colleges is running a special summer course for the Hiroshima city police force so I expect I will be involved in teaching that course. However, it's likely that the wife and I will head down to Kyushu to hook up with our daughter and hang out for a bit in Nagasaki and Fukuoka.
Apart from that, I'll probably arrange some social chess parties, and of course I will continue to accumulate satoshi, Hive and CTP tokens, and promote my "Beginners Crypto Course" throughout the summer. :)
