Russ, what's the worst that could happen? You could get a male LMB and have lots of LMB and large BG for the kids to catch. Read Jayman's post on his kid's pond where the small LMB literally jump out of the water to hit his 5 year old's Rapalla.

Talk about exciting a kid...nothing will excite like a hungry predator LMB (in fresh water at least).
