I've got some bits written - gackable from old LJ/weblog posts, or my notebook - and somewhere I've got the pile of maps and flyers I posted back home, so I should be able to produce something vaguely useful.
How should I do the write-up?
"This time last year I was doing/in [X]" posts over the next few weeks
A few longish posts (behind cut tags, of course) filling in the blank spots from last year
On a separate web site
Try and turn some of it into An Article
Why bother, it's stale news
