1 GuitarFarm 2 years ago Woke up last night to a huge boom. ADT system going nuts. Went out this morning to find bark all over my lawn. This black locust tree has a fresh scar spiraling down from the top. Took out my DirecTV receiver completely. The television has picture (using DVD or game system) but no sound. This happens about once a year but it usually only wipes out my telephone and answering machine. The good news is that all amplifiers appear to be fine.
