Get in touch with nature, but don't let nature get in touch with you! Not recommended for rainy days or when the soil is damp. This is a pretty difficult find already, so you'll want to try coming when there's some daylight to guide the way. (And be warned - you'll want to look out for any little left behind doggie "surprises". Tread carefully.)
There is some trash in the area, but pay it no mind - you won't need to dig through grossness to find this one. You may consider this a "split decision"; may the "forks" be with you!
Major kudos to H2Guy & Countsmama for being FTF! (Impressive turnaround time - the listing's been active for roughly a day!)
