long bike near avalon/stone harbor

I would say your best bet is to head out over the Avalon bridge out towards Woodbine..... Head out to Tuckahoe and there are plenty of good farm roads with wide shoulders and not a lot of traffic.   Just pull up a google maps image of the area and map your ride out. 

Have fun.  Bring a cell phone, and some spare tubes, pumps, etc.....

Avalon Bvld..... Just follow this out on Google maps with the scroll feature and your all set.  You can plan it so that you come back in through the Stone Harbor entrance and it will wind up being a big loop.....

Looks fairly good to me.  To be honest with you the only spot you'll have a problem is between 22-25 on your map.  That takes you on a little trip into down town Tuchahoe.  Right by the train station.  Very nice area but, between 24-25 the bridge is out.  So you won't be able to finish that loop.  So I would stay straight where you would have made the right at the 22 marker on your map. 

What I would do on the way back in is at marker 64 stay straight on Rte 47 just a bit longer until you see Court House Dennis Rd... Make that left and take that all the way into Stone Harbor Bvld.  Then you can take Stone Harbor Bvld all the way into town make a left on 2nd ave and it will run you right back into Avalon.
