[momo fish]

hi.. Been so busy at work didn't realize its a 3 day weekend and my kids love to camp... But I love to kayak as well..

will be heading down to legoland on saturday and would like to tent camp nearby and then kayak early in morning while kids play.. Would love to camp near LJ and fish that area for first time.. Swore I see people camp in san clemente but could be wrong.. Let me know if anyone can help..

also for future as I go camping often all the way as north as san fran, any suggestions where to camp.kayak..

thanks!
