Riding on a column of rising air, a paraglider pilot seeks out the strongest lift which will carry the wing up up up. Once at cloud base, the pilot sends it across the valley or along the ridge. As long as there are thermals to catch, the pilot can stay aloft, and fly from one end of the valley to the next, then beyond. Flights of six or seven hours are not uncommon in this sport, covering as much as 300km on a special day. I think any day you can hang your feet in the air is special.
