All bets are off when it comes to derby time. Spots you've picked, pre-fished, and protected can be comprimised quickly... it's unfortunate to say the least. On the other hand you won't know for sure until you try.I've never heard of baiting rainbows. The most I've seen is what slip knot referred to as "ostrich fishing" where you punch a bunch of holes and deposit salmon eggs at the bottom. On several accounts, people have refered to one hole as the honey hole. It all leads me to believe that rainbows return to certain areas to feed, perhaps out of habit. If one of the holes you're chumming is getting robbed consistently and it looks like it is a decent fish, the best you can do is continue chumming it until derby time, then put a trap in the same exact hole. Good luck.Oh, and obviously... when you put your tip up in, make sure the only bait down there has a hook in it.
