There is a small river near were I live every one fishes the heck out of one hole near the mouth.I have fished up stream within a mile of this hole and had no luck.the bite is great for an hour after light and then it dies completly.do you think those fish shoot up stream? will springers hold in holes further up? should I try to go further up river.I get tired of fighting the croud geting there at 3 am and having somebody show up at 6:30 and stand right next to me!!!
