Canyon, thanks for the awesome crayfish I.D guide. That's really well done. I have to catch a few, but that rusty pic looks like what I've caught in the past.
Don't worry, I'm not putting carp or goldfish in my pond

Re: Tilapia, they are not allowed in IA which I don't understand since they cannot survive a winter here. Hell, I don't think they can survive a Halloween for that matter.
I agree with you on FA removal. Should only be a punishment for bad behavior or a lost bet. With that said I'm guessing it does well as an amendment when tilled into my vegetable garden.
