That's what I'm having trouble doing - there were clip retainer things, which I removed, and I unbolted the screws, and it still wouldn't budge. So it's just an adhesive strip or something holding it on? I'm concerned about getting water (and other weather) in there, anything that can happen? Seems like it's painted so it might be okay. I'm just really concerned about removing it to install the camera, and not having replacement adhesive stuff to get it watertight again before it rains! (Which is often in Colorado). Any danger of leaving half-moon off for awhile?
