Cool find!
Not to argue with anyone, but I tend to agree with Parrothead on this one.
I actually have an arrangement with a thrift-store on my "route" and I've picked up ALL sorts of valuable stuff,
INCLUDING a nice acoustic guitar I gave my 2 year old (...funny my toddler has a nice guitar, she accented with lots 'stickers).

I ALSO have picked up three lawn-mowers, six decent weed-whackers that the "well-off" area I patrol Mon.&Thurs. tossed
(5 of six :Old gas, other had mud clogging the muffler...stupid rich folks toss them if they don't start)...two nice table-saws,
an excellent air-compressor (I gave a relative)...
Heck when I unload at home (transit to scrap OR storage depending) I often feel my neighbors must think I'm going modern Viking, or atleast look like a burglar/ thief...Oh, I HATE when I'm unloading 5 or 6 NICE bicycles especially the childrens' ones how that must look...

Anyway there is a law I will ALWAYS fall back on if necessary that states when trash is put on a curb, in can it then is public property (NO LONGER PRIVATE) ...It's a law OFTEN used by law enforcement to obtain legal search warrants (they search druggies trash, find paraphenelia,etc., then they obtain warrant for entering premises).



Long story short(ER) : Only thing that keeps me from dumpster (besides maggots/smell) is a "No Trespassing" sign above it OR entering premises (Heck there are shops on my "route" that build military grade missile parts etc. ...No-No dumpsters)

Wrote a song about it goes " Dumpster diving, dumpster diving WOOO-HOOO" (sort of the beat of "wonder woman" song really)
Feel free to use those lyrics with the cool guitar my man!
