Seagulls: What's the Deal?

So I went fishing yesterday, and I saw some seagulls. You would expect that. When you go to the beach, what do you see? Seagulls. That's the way it should be. Here is the problem. I see them other places. Walmart in particular. What is it about a Walmart parking lot that attracts them? They are building a new Walmart down the road from my house. I looked over there today and there were seagulls. In the parking lot...That wasn't even finished yet! I think it is some sort of conspiracy that perhaps the seagulls have formed or maybe Walmart. Maybe both. I am going to closely monitor this situation. Beware of the seagulls. Something is odd with them.
