You don't have to use concrete for a footer.. A well dug out trench packed with 3/4- rock would work but you could put a couple in he layer of concrete (just dry bagged) on top of the rock then set your blocks an inch or so into the concrete, bury 3/4 of your first block it should be good to go..

I believe in catch and release. I catch then release to the grease..
