We had a very quick change from bright sunlight to a thunderstorm with lots of rain. We were surprised when 4 families on a bicycle tour were ringing at 8pm at our lonely house in the forest. Storm prevented using navigation systems. They were totally lost, wet and frozen. Using all our towels and some clothes for the kids of them. Heated the field kitchen for a ghoulash soup. Used the team car of firefighters three times to drive them home, last after midnight. Bicycles are still at our place.
We have unexspected guests around two times a year. Could have been worse for them.
