Look at
this 7pm is their scheduled time for the "CITO 11 icons in 11 hours finish" event!
Luckily for us, there is a Shakespeare themed post Geolympix event, details TBA. I want to spend most of the day at the Mega itself, and popping out to find caches within the city for the challenge. Leaving the Marathon cacheathon, and the Cycle series to do after the Geolympix, during the rest of the summer. The cycle series has now been published by the way, that alone contains three cache types, so that would take you to four already...
Hopefully my dad won't be on one of his trips, after all my anticipation of advertising it in my logs etc - I've known about this since it was first proposed in September 2010, I was at that very event - so have been waiting for it since then...
