What we used
• We used fishing rods to hold our line,something else we used, which held our hook,another thing we used, which held our bait,once again something we used, which luredthe fish. The 2 types of rods, open and closedreel. We also used bait because we had ahunch that the fish would not go willingly on thehook. Some of the better bait we used wassome hotdogs, some worms, and corn, kernels
and kernels of corn.

Where we fished!
We fished at the hidden pond, and pond atthe back of EHMIS. The are three areas of
the hidden pond. There is the front, the
part of the pond where I fished, pine treeloop, the part of the pond where the most
fish are caught, and lentic loop, the part of
the pond where the least fish were caught.
