I've recently started kayak fishing the White River near Muncie and I do a combination of the two. If I have a couple hours, I'll put in and paddle upstream 15 minutes to a good spot and hang out there. Then I'll just paddle back downstream when I'm done. If I'm going for 8-10 hours, then I'll try to find an entry point and exit point four to six miles apart. The hard part is arranging transportation for someone to either drop you off or drive you back to where you put in.
