In a time where large machinery is unavailable because of fuel shortages, blasting becomes even more important. It is a viable means of clearing stumps, excavating, and clearing rock slides. Tannerite is available in the mail from Skylight Explosives. Tannerite a binary blasting mix which if prepared on site immediately before blasting, and requires no permit. Speak to Danny Tanner, a G-d fearing man, and friend to the small Jewish community in Eugene, Oregon. A few years ago I took some 19 and 20 year old guests to shoot with Danny. You should have seen the look in the eyes of the six New York yeshiva boys as we set out to fire battle rifles at 100 meter distant dynamite sticks. That was priceless! These guys had never even held a firearm before what a day. Unfortunately Danny didn’t have time to grab his Class 3 guns before that shooting trip. Skylight gives blasting safety classes and this is a very worthy investment. See: http://www.tannerite.com/
