OHM (Observe, Hack, Make) is the latest in the series of four-yearly Dutch hacker camps. 3000 people in a field, with power, internet, and beer. Come and join the London Hackspace/EMF contingent!
It runs from July 31st - August 4th 2013, although some of us will be there earlier to help set up.
Tickets are €180 (~£150), with concessions at €125 (~£100): https://tickets.ohm2013.org/
KLM seem to be the cheapest carrier, but note that they have changed baggage rules recently and no longer give you free checked luggage; hold luggage is now £12 extra each way.
Heerhugowaard is the train station to head for, shuttle buses run from here to the OHM site.
