Nanos! I mean who likes them really? Those select few who appreciate them you really have to wonder about. I suppose they like the challenge,...or they just like the hunt to be torturous. Now we have the Big A Nano, which is a breed all it's own. Don't let the name fool you though! The "A" in Big A Nano, may not necessarily stand for Alabama, or Amazing, or Aggravating, Asinine, ...the possibilities are numerous! There are three different approaches to GZ. Two from the two rest stops, one from a pull off spot. The difficulty or hiking distance will vary depending on your approach. Once there you'll have a nice view of a lovely highway! Whoo hoo what a view! Now's a good time to pretend that you're taking pictures of this wondrous view with your smartphone or GPSr because there might be muggles driving by! Although this stretch of road isn't too terribly busy. Just play it smart for safety & stealth.
As with any cache you may need to BYOBAP (bring your own Big A Pen!)
