I will probably be setting up an Anza Borrego trip in November, but I'm not sure of the date yet. Most likely it will be the 5th Annual Fish Creek and (What's Left of) Sandstone Canyon Apple Pie Extravaganza. The only thing I know for sure is that it won't be the Friday or Saturday after Thanksgiving this year - it may well be Sat 20 Nov, but again, nothing is certain.
Let's see how the temps are in the desert over the next few weekends.
Where are you located anyway? Anza Borrego is in eastern San Diego County.
