According to the pilot, his glider was towed to an altitude of 6,500 feet above mean sea level (msl), which was about 2,600 feet above ground level (agl), and released. The glider achieved an altitude of 7,500 feet, and the pilot continued on to an area that he normally used for soaring. Once he reached the location, he realized the glider was too low to glide back to the airport, or to a known suitable field for an off-airport landing. The pilot stated that his option was to soar to the next available safe field for landing. However, in order to get to the field, the glider would have to cross over a tree line. Upon approach to the trees, the pilot did not think the glider would be able to make it over them, so he set up his approach for landing onto a road adjacent to the tree line. On the landing roll out the right wing struck a tree. The pilot reported that the right wing was damaged, and the tail boom had separated. He also stated that there were no mechanical problems with the glider.
