Congrats to Geofrog on the FTF!!
Welcome to the Minisceongo Creek and Cedar Brook Pond area. You need to look at the Stony Point Tide charts to determine the best time to be here. You should be here when it is at least 1.5 feet high, and that gives you at least a 5 hour window to get these caches, and you shouldn't need more than 2 hours to get them all. This is a lovely area to paddle, you will NOT have to disembark to get any of these caches placed, and the mud is minimal to none if you plan with the information I provided.
Just ask Google to show you the Stony Point Tide chart, and you will see the Willy Weather charts with information on tides and wind. I provided the link in my "Check your Tides Chart" cache.
I asked google to give me information on the safest wind gusts to kayak in, so if you are a beginner, just make sure the wind won't be too strong for your liking.
Have fun!!
