Yes, if you visit San Diego, give Marie at Family Kayak a call. We had a blast with her last summer on the turtle excursion--so enthusiastic and knowledgeable. Also recommend (dead link removed) for Lake Mead excursions. It's the perfect family trip..you can rent sit-on-top kayaks and there are lots...

Have to second the recommendation for Los Jilbertos in Safford if you are looking for fast food or takeout. Super inexpensive and very good!
