If you're looking for Stripers in the ditch and you haven't fished there before then be prepared to lose alot of rigs, jigs and gear.
DO:
1. Be very cautious on the rocks, they are treacherous and slimy sometimes.
2. have a spare light at night
3. Use a heavy rod and reel setup, there is no stopping a big striper in the canal with a 4-5 knot current with wimpy gear.
4. try your best to revive released fish so they don't just float down with the current, I've seen it before

5. Ask questions politely if you are having a hard time , most people will be helpful some will just groan or give misleading info.
6. have fun
Don't:
1. leave your trash behind, you bring it in , you bring it out . it's that simple. It doesn't hurt to toss afew other things in the barrels also. I myself can't fish among trash so I usually clean up before I start fishing.
2. have high expectations, the ditch is a hard place to learn- it takes years and good info.
3. stick to just one method, if chunks aren't working then try jigs off the bottom, or plugs if there are rising fish.
4. don't just stick to one place , the fish move too. What may have been good yesterday may not be good today.
5. cast near boats going by, and watch out for the wakes
6. fish near seals, the seal will cause the fishing to slow down.
7. finally don't listen to me , I have yet to land a 20 pounder in the canal

maybe someone else can help you too
