This cache is near the entrance of Arnold's largest city park. This park has everything you would want in a city park, except a public pool. It is very busy, especially on the weekends. You WILL get muggled while looking for this cache. Most will drive by, but some may walk up on you without notice.
There is a very interesting sign, not far from the cache, titled "Arnold's Wetlands". UPDATE:The sign was vandalized so now it is just a bulletin board. It gives you lots of information about the area and the wetlands. When you find the cache, remove the lid and leave it, (you will find out why). Take the container to the sign and sign the log there. It is a regular container full of goodies for the kids, so it may take time to go through it. The muggles will think you are educating yourself and not pay any attention. If you do this, the cache location may last for a long time.
