The Slidewinder has been removed from the area and banished for too many White Russians, and the cache has been modified accordingly. When you meander over to Stage 1, perhaps with your only form of identification being a loyalty card to Ralph's take walk over to the short bar stool. Take a look on the post on that crazy stool and you should see some information, which includes some ages, a date, and other information. Focus in on that label and not your beverage label, partner.
To get the coordinates to Stage 2, do the following:
Take the last digit in the Date section and set that equal to X. Stage 2 North coordinates then are as follows N 41 4X.94X
Count the numbers and letters in the Order # listed and set that equal to Y. Stage 2 West coordinates require a calculation.as follows (Y*32.5)=Z. Then add the answer for Z to the Stage 1 coordinates.
While you mosey down the plush Green Trails, make sure you don't get Tangled up in the Wood at Stage 2. Perhaps you can enjoy a nice Sioux City sarsaparilla on your journey. Or at the very least a White Russian.
The Dude abides....
