Here's a puzzle cache challenge for you. The cache is not at the listed coordinates, but is good place to park.
This is a "PodCache". A combination of podcasting and caching. Here's the idea: an MP3 audio file that has clues to lead you to a cache. Ideally you download the MP3 into a portable player and walk the route that we describe listening to our voices in "real time". If you don't have an MP3 player, consider burning the audio to a CD.
Update 6/3/21: HERE is the link that currently works
NOTE: Things have changed quite a bit in downtown Escondido since we recorded this in 2005, so not everything that we say in the audio lines up. But most people have been able to follow along and figure it out. Good luck!!
