Latest (Jan 28) general conditions report from R2R: "We are beginning a short period of cold mornings and warmer afternoons. With a mild freeze overnight, most trails should be good to ride or hike on this morning. Look for them to soften by late morning however so at that point you should confine your use to only the sandier trails. Remember - If you are leaving tracks, it will be time to turn back."
When planning your trail usage this weekend, please remember that trails in the Hulls/Crestline area are generally sandy and well-draining. By contrast, Tablerock trails and most Military Reserve trails are generally clay/sedimentary and are not good choices when not frozen. Happy trails. (Thanks Tom !)
