My daughter is 2 yrs 8 months and loves messing with rods in the garage, as far as fishing goes she has a toy rod and magnetic fish for the bath which she loves trying to catch. Yesterday I took half day off work

and we went up to Cogra Moss for an hour ( keep it short so she doesnt get bored ) anyway we got 2 fish on the dry fly, watching the dryfly kept her interested and I let her hold the rod while I controlled the line bringing the fish in. I couldn't bring myself to let her see her daddy become a murderer so we let the fish swim off and she happily waved them goodbye, after that every rise was her fish and waving to them kept her occupied for the rest of the hour.
I will wait untill she is at least 4 yrs before attempting to learn her how to cast but I think we'll have a few more of the one hour trips over the summer.
