Not really. The times Ive been asked this question I've tended to throw up the number 7, because that seemed the general consensus. But I don't really do lucky numbers.
I have one lucky charm though. A 3 centimeter long antler I found in the scottish highlands when I was a kid. A once in a lifetime find, and easy to keep in my pocket. Also, even though this one is small, antlers are the sex. Booya!
Tried to find a picture of a similar antler, but apart from some sawed off tips(which dont count!) I cant find any tiny antler like mine on the web. Maybe it truely was a spectacular find. >.>
