heavy traffic, no sholders, from cape may- lewis ferry, but once you get to the shore route there are well designed bike/ped lanes marked. FYI: there is a 12.0 mile trail to/from RBDE that was just opened, an alternative, but i have not tried it.
as always, be carefull, watch for those idiots, and don't let your guard down!
enjoy de shore, where are you headed? we used to hang out in rehobethe beach or bethany, but have spent time as well in Ocean City, MD... but that's another post!
