This cache is not in a non-safe or prohibited location. You need not mess along side the already messed up S-curves. i.e. don't be stopping on the freeway or looking near RR tracks or crawling underneath prohibited things!
Note added 4-Jan-2008: I have changed the difficulty rating to 2.5 since previously undisclosed information is now in the description. Note logs of 4-Jan-08.
Note added 23-Aug-2003: I have given this cache a 4-star difficulty rating due to the numerous people who are unable to find it on their first attempt. Be warned, however, that just about every clue you will need to find it is included within the logs. If you are up to the challenge, then do not read the logs. If you are a pansy who gives up easily, then go ahead and look. Also, a reminder to those who enter logs - encrypt anything that is a hint.
Please be sure to return this cache to the exact spot where you found it. It seems that someone once attempted to hide it differently, resulting in two caches from mid-August 2003 thru mid-April 2004.
