Follow the clues and a host of characters to save the day. Prognosis Negative will leave you as dizzy as your virtual counterpart, and have you wondering where the line between real life and the virtual game is drawn. Good luck.
Walnut Creek Park is home to many great caches. Get yourself there; we suggest the lesser known southern entrance.

This cartridge deserves a six-star rating. Some time is required for this quest, but it's great fun.

Best Wherigo yet. So much forethought to the story. A few times we got stumped and had to start over, but it was well worth it. Thanks for the adventure.

Well done, well crafted Wherigo in a great park in Austin. It played well on a Samsung Galaxy III phone using the Where You Go application. I found that the OpenCycleMap available through the map selection to be the perfect map to use for the park, as it showed all of the major trails in the park. If you did everything without making mistakes, and found everything quickly, you could probably complete in about 90 minutes, including the trip back to the starting point. But otherwise, I would allow at least 2.5 hours to complete.

I finished up this cartridge today on the way to work after running out of time on Saturday. What a great adventure! The cartridge worked flawlessly on my Samsung Galaxy S3. I think I worked at it for 90 minutes on Saturday and finished up in about 45 minutes today.

Another incredible adventure. I had never done a Wherigo cache before, but I imagine that this one would be hard to equal in frustration and excitement. This took my son and I 3 trips... The first got cut short due to dinner plans.
The second trip was intended to be a quick wrap up, however, it was anything but. We were going back and forth for hours. I don't suggest this for most 5 year olds, but my son is a real trooper. I was stuck at one point and just couldn't seem to go any further. I revisited all the previous locations looking for anything I may have missed. At dusk we called it a night, also being half-dead (virtually and otherwise).
I had emailed a group that had done this over a year ago, and they gave it some thought, but really no clues surfaced. But in the process of discussing it and tossing it around while I should have been sleeping, I thought of something I wasn't sure i had tried.
So, we returned this evening. Turned out that my inkling was incorrect, but for some reason unbeknownst to me, the thing that got me stuck resolved itself on its own. Not sure if it was a cartridge error or operator error, but whatever happened, it was fine with me.
And that led us to the end. It could have been smoother, but that's ok. It's completely memorable this way! Fave point and continued kudos for the incredible caches!
