Input:
We already had one of these Big Bobbers, and it was so popular, that we puchased it for a family member as a birthday gift.  He loved it!  My only complaint was that I was unable to track to shipping of the purchase for some reason.  It did arrive within the time specified, but there must have been something wrong with the tracking/shipping feature.
