David,
While it is, in fact, some consolation, I'd rather have read that you have one that you bought four years ago and it's still working just great on the original battery with at least a dozen uses per day. /w3tcompact/icons/smile.gif I am, however, encouraged by your faith in and enthusiasm for the system. I know St. Joseph County isn't particularly known for being any sunnier than Allen.
Since I don't live on my property, I do have a practical question. I'm assuming there's some little solar panel so here's what I wonder. What keeps snow off it so when the sun does come out the rays can get to the panel. I ask because I won't be there cleaning it off as I won't be living there.
