This cache is located on Sterling Boulevard hence the name.
You can park on the service roads that run parallel to the boulevard, but the one uphill has no parking signs, though you may find a spot in front of someone's house. Downhill is a better option. Across the street is another option. You could also try parking on Argonne as I think you can walk over from that street. Alternatively, you could walk over from my other close by cache which is about a 1/3rd mile walk. It's also not too far from Claude Moore Park.
Congrats to pseudoprime for the FTF!
