island, I'm sure you're right. But alas a truss is beyond my DIY abilities, so I'll have to live with more posts than I'd ideally like.

(One of these days I'll have the garage rebuilt to a two-story, sort of a carriage house thing. Maybe I'll have a professional build a proper carport then.)

The roof will be tinted (smoked gray) corrugated plastic. Light, cheap, easily repaired, lets light in while blocking rain. Flat with just enough of an angle for drainage.
