Great fish, and great start to your ice year!
That's a huge stocker rainbow. Mike must have invested in some brood fish for the metroparks. Also send a picture to him and they will post it on the Metroparks blog. Helps him get more funding for more fish in the future. PM me if you need more info.
We were out many years ago fishing Steelhead through the ice at Edgewater Marina, had 14" of ice underneath us there that year. I watched a guy pull a 30" 10 lb. steelie after a 30 min fight. The rainbows are quite at home in cold water and fight forever.
Spud one, spud two, if it went through, so will you!
