The page you linked is where upcoming CLD Summits will be posted for registration. Typically, CLD Summits have been held in the September to December timeframe, with emails going out to local CLDs. If you haven't received an email in the past, it's likely because there was not a summit in your general area; however, if you have budget and are willing to travel, I recommend checking back on that page to see if there are locations you would be interesting in visiting.
