Jim:

I am having a hard time trying to remember where I saw a project
involving garage storage. *The main thing I remember about the project
was that the shelf supports consisted of two boards (2x4 perhaps) with
a triangular shaped rib from plywood forming a sort of I beam type
structure. *From what I remember the article was in the last 3 years
but I can't recall the magazine I saw it in and I haven't had any luck
with google or searches of some of the magazine websites. *I am hoping
that this brief description is enough to trigger someone's memory.

I can't remember what it was either, but try Family Handyman as well
as Wood, Woodworker's Journal,
or ShopNotes. The on-line indexes might help.

Was this strictly wood storage or general garage storage?
