No real twisties to speak of. Most of your twisties around here are mountain rides. Some low mountain places never get snow. Usually 4000 feet and up.
You could tool around Hemet, Borrego Springs and Julian and any of those back roads down to the 8 freeway, staying away from Salton Sea. The road up to Idyllwild could be clear, you'd have to check.
If the weather bucks up our own Route 2 is World class and back roads to Big Bear. I did three nights and never got more than 120 miles away from home!
Reserve the bike and ride according to weather. There is a little loop up Highway 38 out of Azusa and Glendora Ridge and Mount Baldy.
We rent rooms to travellers and offer advice, guide or just leave you alone. You could ride two or three days over on the east side (Claremont) weather permitting. (Glendora Ridge/ Baldy/Big Bear/Idyllwild/Joshua Tree.
