I am taking my Son, and nephew down to PINS this weekend and was thinking about renting a Kayak in Corpus. Is there any place that is not too far off the interstate? What is the going rate for Kayak rental? Also, how in the heck do I keep my ice from melting so fast in my coolers. One of my ice chests holds about 12 bags, and last time we went, the ice in it had pretty much melted in a single day. I have heard about partially burying the ice chest in the sand, but we don't set up camp until around sundown and are constantly moving otherwise. Would block ice help? Thanks in advance, Jeff.
