My husband thinks I'm a good organizer, but he also enjoys orderliness as much as I do, and since we are both firstborns with typical firstborn traits, our mental states are so much better in a tidy organized environment.
Hubby uses a pegboard for the tools he uses most frequently to keep them in easy reach.
We have 5 bikes in the family, and he uses this track system high and low to store them off the floor so we can still park our cars in our somewhat narrow garage.
These track systems can be bought at home improvement or hardware stores.
They adjust to store all kinds of things you might have in your garage.
Hooks can be used for storing things like ladders.
Shelves work great too, which we have in a little alcove, and they can go all the way up for lots of vertical storage.
These links have some great additional tips and photos for garage organization:
I Heart Organizing--labeled bins, coat hooks for dog leashes, utility hooks for golf bags
Good Housekeeping--lockable cabinets for hazardous materials
HGTV--Categorize and group items
Hope this is helpful!
