I was up north for the past week. Tried out the Aguasabon River while I was there. Fished the mouth and worked my way 20 miles up. It's a river that empties into a series of small lakes as it goes. Only did the bottom end, but the river goes on for miles. There are pickerel and pike and rainbow and specks, and who knows what else.
I only got Pike, lost a few up-river, but landed this nice one in the morning fog, off the dock.
