i decided to extend this and include more dates... you can download these files, stuff 'em in your calendar, see what's going on -*tons* of events this year, with dozens of regionals this summer alone. (the files are 'ical' format, ics files).
my list for 2007, including regionals & other events:
burn calendar for 2007
burn calendar (csv format)
burn dates till 2012, 'equinox' (solstinox) & gates:
burn dates 2008-2012
2007 ranger training schedule (contact rangers for info/rsvp):
ranger training 2007
2007 dpw work weekends, (contact dpw / foxtrot before heading out!):
dpw work weekends 2007
all public info, all unofficial, just my list and subject to change. double check info before travelling. does not contain any MSG. some events listed as regionals might not actually be regionals, check the burningman website. zero calories. feel free to send updates. may contain phat. also, if you don't know where an event is, neither do i. sorry if i didn't catch your event, post an email or comment and i will add it. enjoy!
note: if you import the file twice you may get duplicates, depends on your setup/software. i suggest using a separate calendar, test things out first.
fyi, the location field appears to get munched importing into google -takes city/state, but not much else... so notes like "location TBD" get lost in translation. and accented characters are dropped by remotecalendars (plug-in for outlook).
all in all, everything i tried worked pretty well. 'subscribing' will keep calendar items up-to-date when new events are posted. see other post for details.
your mileage may vary.
