You are not missing anything. The services at the trail heads are limited to none at all. I found from Boone to Clinton there are Casey's stores near several trail heads, but from Defiance to Boone, services are very limited. On my trip a few weeks back, I had to ask others for water two times because there was simply no places to get water. Be prepared with your own water and do not rely on any services at the trail heads.
