Hey Onelove,
Found your Summit Valley access area this morning at the top of that hill. Fished for about 3 hours till my fingers were numb. No stipers but one lovely channel cat about 10lbs.
My map shows another road that comes out east of the airport called Las Flores that runs all the way down to 173 that crosses the duct about halfway to Silverwood from there. Have you or do you know anything about this spot.
Let me know next time you are going out , I'll see ya out there.
