I guess I couldn't wait to find Organon since I already figured out the puzzle, so I went for it this afternoon. After battling a whole lot of traffic, it was an easy walk through the woods of Echo Lake Park in Mountainside.
After that, I endured even more traffic (Apparently, Central Jersey was just choked up with Friday afternoon traffic!) and went for Agi's FIRST AID Box in Middlesex. I didn't know if there was a closer place to park, so I just left the car near the sign at the first stage and bushwhacked into the swampy wooded area. This was indeed quite a wet area and the grass covered the puddles, so I stepped right into the water a few times. Good thing I brought extra socks and shoes.
After that, I went to Edison to get dinner and even more Asian pears. Yes, there was a traffic delay there too, even though it was after 6:30pm.
