Here is a trip that is posted over on the Planet Isuzu site.
Box Canyon/Coke Ovens
Meeting at the pull out just east of the railroad tracks (east of Florence) at 8:00AM on Sun. Sept. 21 2008.
I plan on being there and VCamilo is going to try and make it.
This trail is an intermediate trail (disclaimer: I have not done this trail in a few years so the monsoon rains may have changed the trail somewhat). The last time I was there stock 4x4's made it pretty easily.
So all you 'Zonies come on out and join some other Zu's and friends for a fun day!
