I have traversed all the roads mentioned with sedans. You have to be careful. For French Joe Canyon a short wheelbase is an asset (i.e. an economy class car) because of the largish "speed bumps". The same is true for Fort Huachuca with the concrete gullies where washes cross the road. Be advised that the last steep downhill portion of California Gulch (which I have done in a sedan) is now closed and you have to walk in the last 1/4 to 1/2 mile. I understand that you can come in from the other direction, but I'm not familiar with the road. You can also get into Chino Canyon with a small car. The going is slow, but it's not impossible. I haven't heard of any reports of Black-capped Gnatcatchers from there this year but there are at least two reports from locations further north, nearer to Phoenix. Check AZ/NM Birds on the net. To sum it up, most folks don't even think about a 4-wheel drive when planning their AZ birding trips. They cost too much. You could do most of the trip with a sedan and save the rougher canyons for the last couple of days, switching vehicles near the end, if you are concerned. I rented a 4-wheel for the first time last spring to go into Chino for the Gnatcatcher, but I had only one day and wanted to be sure I made it since there had been a lot of rain, and Gary Rosenberg had scrapped an earlier date because of the road conditions. As it turned out I didn't really need the 4-wheel, since two other parties came in after me using sedans. So just go and enjoy. Paul O'Brien Rockville, MD pobrien776@aol.com
