Joined a group with the lady to get wet, dirty, bruised and cold; the activity is called cave crawling and the site was Klövbergsgrottan in Tyresö.. The place did not disappoint, with some 362 meters of tunnels and chambers, containing "spider rooms", "art rooms", sliding slippery slopes and various types of sharp rocks and stones and water dripping from the roofs.. In all, a great Sunday afternoon that was finished off with hot dogs on an open fire as darkness fell together with a soft rain..
