I came across this neat website/app called meetup. I found a local kayak fishing group for my area and can see when others are going out and can tell others when I'll be out. I'm sure you can find similar groups in the area you live in OR create a group!
For anyone that is in the Southern California area the meet up group can be found here:The OC Kayak Fishing Grouphttp://www.meetup.com/Kayak-Fishing-OC/
I'll be going out on the 17th to fish the Dana Point kelp fields on my new TI with a coworker. Please come along if you are free that day! Direct link to June 17th outing http://www.meetup.com/Kayak-Fishing-OC/events/187043802/
