I haven't even made my first payment on my HCH II, and the weatherman announced that "potentially baseball sized hail" was on the way. We didn't think anything of it until we saw the direction of the storm. It was right towards Menomonee Falls, WI (20 minutes northwest of Milwaukee). Needless to say I was terrified. We have a 1 car garage. My girlfriend's HCH II (brand new also) had the garage spot for the night.
We decided to be creative... She parked her car as far forward as possible, and I parked mine behind hers (we left the garage open). We then proceeded to cover the back end of my car with blankets (only the back window and trunk were exposed).
We then stood and watched as the hail started to pellet my car. We slowly started to notice the hail getting bigger and bigger. We ran back upstairs to get more blankets. Watching for a bit longer convinced us to take drastic action... we covered the back end with pillows.

The hail continued for what seemed like forever (probably like 15 minutes). After the rain had finished we walked around the driveway and found some pretty big sized hail.

After inspecting my car as well as I could in the dark(at 10:45 pm), I only saw 1 spot we neglected to cover. It is a very small dent and barely visible. It looks like I got out lucky.
Ok... maybe I'm being a bit wierd about protecting my car... but I'm sure at least 1 other person out there would've tried the same thing
