Linux Beer Hike is coming to Killin in the Scottish Highlands this August. Spend the day doing outdoors activities, and the evening sampling beers. There might be some computing in there, but who has time for that?
Plenty of good cycling in the area - as our Dundee correspondents can tell us. Offroad Sustrans type routes on Loch Lubnaig and Glen Ogle. Youth hostel and camping in Killin, or B+B etc.
If you haven't got holiday plans, this is well worth coming to. I've been to three so far, and enjoyed myself every year.
