lol I thought guerrilla growing was about growing deep in the woods, away from society, Its does not sound very guerrilla like, the location you described to me. Its just simply, way to sketchy, to have plants close to so much foot traffic. For starters, the smell once it buds will be unreal, every person that walks by will be able to smell it, and most likely, you will leave a heavy trail beat down in the grass right to it, making it very easy for anybody to follow the trail right to your plant or plants. Have you thought about how your going to carry a big old bucket of water to your plants at least once a week without being seen? I would recommend not growing there, and finding some areas a little more "secluded", or you could just grow indoor.
