Fish Hut and Absolutely Fish are like 5 - 7 minutes apart. If you head out Route 46 West, you will come to Fish Hut first (although you do have to hit a u-turn to get there as it is on the East bound side). When you leave there, there is a traffic light right there where you can make a u-turn to get right back onto 46 West. The only reason I suggest this way is because Absolutely Fish is right where 46 meets up with route 3, and it gets kind of confusing at that point. To get to Route 4 Aquarium, not taking back roads, you would have to back track on 46 East, get onto 17 North to Route 4 West. I know, it all sounds crazy, but that's the best way. If you guys work out that NJ LFS trip that works with my schedule, I will be more than happy to join you guys and show you around. I am always heading out to these spots.
