Picking up objects on the side of the road is often not the best idea, because someone might come back looking for them, they never look as good in your room as anticipated, and...her name is Denise, a-hole, she's not an "object". Finally putting roadside crap to good use: John Wilson.
A San Francisco transplant now tinkering out of Roanoke, VA, John Wilson custom-makes clean, sturdy man-furnishings out of collected "roadkill signs", truck tailgates, and other auto-detritus, after getting his start welding riggings for Burning Man, while desperately trying to avoid becoming one himself. To commission a piece, chat with John and agree on your signage (picked from his stockpile) and general table-type, and he'll custom shape and weld a steel frame around your sign, paint or powder-coat the whole thing, and slather the top with a relatively low-toxicity epoxy resin which he's found makes "the colors pop" -- although that might be a side effect of his other, high-toxicity resin. You can also choose from an already-made store of junkyard beauty, including tables like a way-old green Ford tailgate over a green powder-coated steel frame, a sleek job with a "Speed Limit 30" top and gear-accented base, an unpainted endtable supported by an old twisted crankshaft, a yellow "Railroad X'ing" breakfast table, and a squat stop-sign sidetable, destined to be the most brazenly ignored piece of furniture in your place.
John's also got a slew of non-functional "fine art" items twisted out of found metal objects, like the upright, red/gray "Mutated Snail" fashioned from an old I-beam, or a wrench & metal chain piece titled "Road Runner" -- also an apt description of Denise, once she learns to avoid your repeated curbside pickup attempts.
