is a bait tank over kill?
do you really need a mobile phone? why not just find a pay phone when you want to make a call? or just check your messages when you get home on your home answering machine?
so a bait tank is like a mobile phone, we all have them for convenience and to a degree has become a necessity. your question is why not just drop a bucket every once in while? i think you can answer that for yourself, but for the most of us here we rather have that little bit of comfort and luxury of not having to drop that bucket over the side "every once in awhile".
