There are two 'groups' of caches in the series that can be done from the Parking Waypoint:
1. GC4F7Z0, GC4F831, GC4F7YE, GC4E3XA
NB: After doing GC4E3XA, return via GC4F7YE to the Parking Waypoint
2. GC4FMRD, GC4FMQN, GC4FMRC, GC4F7ZF, GC4EA0N
NB: It is best to do this group in the listed order and retrace your steps back to the Parking Waypoint ... you are NOT advised to take a direct route between GC4E3XA and the Parking Waypoint (CO has done this, but not in tick season).
There are also some other accessible caches in this area.
The Gnome Hunters
This series pays tribute to cachers who have completed the Serpentine Gnomes series and celebrates some of the great logs written by said Gnome Hunters.
Gypsy Roaming
Gypsy Roaming on Serpentine Gnomes 5: "... I'm in hell, at the mercy of an 
cache hider. Thick bush, loose rocks, sliding down & across have reached the crawling on hands point ...".
Your log on Gnomes 6 is also highly quoteable Gypsy Roaming ... but I loved the imagery in the above words.
The Cache
The cache is an ammo box in an obvious spot. Shouldn't need to crawl for this one. There's a hint in case your GPSr won't play the game here.
