Robert, love your first two and they would be on my list as well. Ohio, also like your #1. We are so fortunate to be living in a country where everybody can enjoy fishing, not just the rich. Here's the rest of my top 10.
4. Teach someone to flyfish.
5. Buy a kick boat, you'll love it.
6. Pick up trash around the water left by others.
7. Leave farm gates the way you found them, open or closed.
8. When asking a land owner to fish his pond tell him you're strictly catch and release unless he's hungry for fish, then volunteer to provide him a meal of cleaned fresh fish direct from his pond. This approach has gotten me permission to fish some fantastic farm ponds throughout the years.
9. Browse through the flyfishing section of Ebay occasionally.
10. Read this board as least weekly, daily if you can.
