If you are not street-legal but need to cross the highway, this is one place where you can cross under it. This is a culvert that goes under I-10. I recommend only ATVs to go through the culvert. If you are north of the highway, you can get to the cache by ATV, UTV, 4x4, or a small pickup. A UTV could go through the culvert if you can detach that pretty top. All vehicles can go about a mile west to the bridge on Ramsey Mine Road to cross over.
If you are south of the highway, you could get to the culvert and then walk about 1/4 mile under the highway to the cache.
This cache is a large Altoids tin with a logbook and a pencil.
Congratulations to rorcutt5 and jypsyj for getting FTF together!
If you find any problem with my caches, please write a NOTE. If you just say something in your regular log, I probably will not see it. When I get 22 logs from a finder and they are all identical (copy/paste), I read about 3 and then delete the rest of them unseen. If you leave a note, I have filters to filter them out into their own folder so I will see them. Of course, any DNF will also filter out, so I will find them as well.
