Yea man, Menards has 1/2 and 3/4. I'm going with the 3/4 for my racks. I have it all planned out to build two 28 qt racks that are 8 high and then a 20 tub baby rack. That only takes 4 sheets if you cut it right which is only about $140. Not bad for 36 snake homes! Thats without the tubs ofcourse.
Where are you at in Iowa?
