I lived 6 blocks from the beautifull park in Jordan, MN. called the Mill Pond. The Mill Pond park has a nice little swimming beach with a beautifull fountain, ball park called the Mini-Met. One Saturday I grabbed two fishing poles and walked with my boys, ages 6 and 8 down to the Mill Pond. I had the boys drop the lines in using worms bor bait and after 15 minutes my youngest son caught a 20" carp. I had my son release the fish but it will be a memory he will have forever.
Teach a kid how to fish!
