Is this common?
 

I have been getting interested in Trapping and checking out youtube videos and ran accross this one.

How To Set a Trap PART 1 - YouTube


Is this a common way to trap?


And what all can you trap using this method?

Get rid of the wax paper it's not needed if your going to bring extra stuff out and are worried about freezing stick your trap in a ziplock bag, use sheep's wool instead of cotton balls. And then you can use that to trap just about everything. Your also going to need a bigger hammer, I'd recommend the ground hog by Minnesota Trapline Products, they can also supply you with every thing you need for trapping.
