You will be quite exposed retrieving this cache. Although this cache was placed with permission, certainly not everyone in the vicinity will know of its presence. Please be sensible and respectful of others. If you have any trouble, the good news is that you'll likely be able to find legal representation close by!
Bonus points (and maybe a prize or bail $) for logs that include pictures of you doing what needs to be done. I won't mind spoilers on this one.
