Beanzor, it's up the 87 past Sycamore Creek. There's a sign for it, Mt. Ord.
The drive up to the AO is dangerous (no guardrails and some sharp turns with fatal drop offs), so, go slow and make sure you have a truck with ground clearance. There's a little hill you gotta get up to get into the parking area.
Wish I could go - I'll be at Coachella.
Have fun, dudes.
