Tme of year to get it while the gettings good. Don't know if you plan to do the Appalachian trail or more local to you like Valley Forge but will say colors are beginning to pop at the Wissahickon. I stuck to running Forbidden Drive today. Warm but a little too humid for my taste. Sun came out some by late afternoon. Beautiful atmospheric low fog over the creek looking into the curve from the sealed drinking fountain that looks like a mausoleum to Rex Ave bridge. FD was soft from the rain and fallen leaves. Nice time of year to be outdoors. If we play it by ear I'm sure we'll have plenty of dreary days before the snows come to dust off the ski gear indoors at Big Snow...I am leaning towards going hiking with my husband since it will be sunny and nice hiking weather, according to the current forecast at least.
