Here's an option. Cheap taxi $5bz into town where there are plenty bikes. I rented two adult and one childrens bike for $160bz a week. The bikes from Joe's were all brand new. The baskets in front held our water, snacks and a bike lock. In three weeks we only locked our bikes up a couple times. My pic in the Vacation Photo post will give you an idea of what to expect. If your an experienced rider, the beach ride from the cut to as far south as you want to go is great. Of course a day spent north of the cut is a must. Or just cruisin.
Enjoy, Jeff
