1976 Dragon Rally, minus 7C camping in Snowden. Feeling pretty miserable that Sunday morning, frozen and hung over whem some flash German git who had ridden from Elephant Rally in Germany on his brand new BMW and arctic suit etc. They then started telling us how we had it soft - it was much colder in Germany etc etc. They were sooo much better equiped than we were. (I was on a 1960 velocette venom with black plastic bags as wet weather gear) They camped next to us looking down on our pityfull play tent plastic sheet and primus stove. They put up a flash arctic explorer tent then took out a state of the art gas stove (it was 1976!) - We grinned when it wouldnt light he was out of gas, he shrugged pulled a spare tank from his panniers and gave us a we are ready for anything look. He unscrewed the cylinder and oops he wasnt out of gas the jets on the gas stove were just frozen up. The tank took off like a rocket and the gas caught fire - it shot straight into his tent and it went up like .... well like a tent full of expensive gear on fire.
We would have helped but we didnt know much about such high tech gear and we may have broken it - besides we were laughing too much.
