Park-n-grab at Ladera Shopping Center.
This is located at the end of a row of parking spaces far enough away from the store where muggles on foot shouldn't be a big problem, but there is a fair amount of traffic so some stealth is required.
If you can park in the last spot at the end of the row, alongside the hedge, you've got it made. The car will be a good muggle shield.
The container is a 2x4 black box with enough room for logbook, pencil, and some very small swag.
There are some stickers so you may want to put on your geocaching gloves for this one.
