Mine is somewhat similar to yours Art. Just more efficent and a little more "stealthy". I have an actual metal bike rack on my covered patio. A larger unit that accomodates 10 or 12 bikes, it happens to sit in front of my bedroom window. The "shock and awe" componant is in the form of a 60lb. brindle pit bull :shock: she would'nt hurt a flie, but she fronts well and nobody has really wanted to go any further as of yet. The second componant (stealth) is my red dachsund, who just happens to like snoozing in front of the bike rack! :lol: His teeth are just as big as the pitts, heck his body is almost as big as the pitt's, just got no legs. And that "little" so and so will hang a tooth in a stranger in a happy heart-beat! They just are not likely to see it coming! And their barking is usually enough to ward off anyone anyway. :mrgreen: Later & PEACE!!!!
