THANK YOU!! YES!!!! I thought I was the only one!!! I can totally understand your PANIC!
I told my buddy that the first night I was out there that the cows chased me. HE DIDN'T BELIEVE ME! I was walking along, and I noticed one following me. I didn't think anything of it. It stopped, and then I got some distance. A couple seconds later, I hear it trotting, and I turned around to see this cow bearing down on me. What the...????
The others took his cue, and all of the sudden, there were 30 cows bearing down on me.
I didn't know what to do. I kept repeating to myself "...just a cow....just a cow....just a friendly cow....just a friendly killer cow!!!" I ran for the closest tree I could get to.
My buddy said "OOOOOOOOoooooooooooh...they probably just thought you were gonna feed them, and they wanted to be first in line". I said "You didn't see it. They were after ME! They looked like I was the only thing that they wanted to eat!" My buddy just laughed at me because he thought I was kidding. This fool who is afraid of grasshoppers, was laughing at me. At least what I was running from was bigger than my thumb!

After I got out no worse for wear with a slightly elavated heart beat, I started to think that maybe because there are soo many young cows out there that maybe the bigger cows were being protective. It was getting dark, and I was completely camo'ed. I think they didn't know what I was, but percieved me as a threat. I dunno...but it got me wary of them in the dark. They don't do anything when I go in in the light, but the dark is a different story!
I can laugh about it now, but dang, that was freaky!
