Where are you? You can still come up the 14 to the 138 east to my knowledge. The 138 east is closed after the 15, but I believe you can still take it from the 14 (Palmdale) to the 2... unless they've closed the 14 through Canyon Country, in which case never mind! Check before you leave.
From the north as Redneck girl (sp, sorry) says, you can make it.
