Air Compressor

I mentioned in a previous post that nobody told me I needed an air compressor to use a nail gun. Well I stand corrected, sort of. I was talking with my boss last week about purchasing the nail gun and he actually emailed the picture of the nail gun from Harbor Freight, along with a picture of an air compressor. He didn't actually say "you need this for the air gun to work" so I just deleted the air compressor picture and thought "why did he send me a picture of that that? he must be tool happy and thinks I need every tool under the sun all at once" LOL I'm an idiot.
