Here's how I store my coal right outside the patio door. It's a Waste Management Bagster which can be had at most hardware stores.http://www.thebagster.com/
What I like about this set up is unloading. I can back up my Ford Ranger and roll the load off with a load handler. For those that don't know
what that is...http://www.loadhandler.com/
I generally get about 1100 lbs @ Casey Kassa at a time. The first load pretty much rolls right in. The second load I have to do some raking to
"make room" for the rest as it comes off the truck. Main problem with the Bagster is that it will bulge out beyond it's 4' x 8' size, so keep that in mind.
There are straps on each side so I have the back side tied up on one of my wood racks for support. This is my second year using this.
Beats shoveling. This is about 2300 lbs.
