Congrats on your new 85CG! I’m in SF as well (Hi neighbor!), and didn’t find anyone particularly interested in my full-size carton last year. I wound up putting it on craigslist for free and somebody picked it up for some use having to do with animals.
You could call Harps Etc. in Walnut Creek… I don’t think they will pick it up, but if you have access to a vehicle large enough to transport it they might accept it as a drop-off?
It’s sort of a shame since it is an item with some value, but it’s just so infrequently people need them. I think my teacher had some idea for community storage that sounded like a natural to me. Anyway, I hope the timing works out for you and you make someone’s day!
Hope you enjoy your new instrument!
