Hola, I was just down there last week, and the loop from Wildwood Crest to cape may back to rio grande was decent. the only annoying bits were the bridges on the Wildwood -> Cape may portion dont have adequate room to get past, so you either have to floor it or walk the tiny side if there is traffic.
Cape May is a good route. You could go to the lighthouse then come back and hit Route 8 (I think that's the route #) and go north for a couple of miles. They even have a bike trail that was pretty nice. Was there about a month ago. They don't charge cyclists tolls on the bridges. I was in Avalon and rode north to a little town (not sure of the name - not from there), but that was a good ride. Little traffic. I found Wildwood to have a lot of traffic, especially with people going to the boardwalk.
I want to know why Hemingway cracked. Sometimes truth is stanger than fiction.
