So, you want to get to the Quinnstitute? Your sanity should be questioned, but…
From the West (e.g. SF, Berkeley)...
Take 24 East all the way to 680. You’ll want to take 680 south, but stay in the left-most lane, as you’ll be taking the Mt. Diablo exit (not the one in Lafayette) which is on the left about 50 feet past the split. The second light is Oakland, where you'll take a left. Continue on to the stop sign, which is Trinity. You'll turn left to go across the overpass....
From the South (e.g. Sans Ramon or Jose)...
Take 680 North to the Ygnacio Valley Road exit (just after the 24 split). The exit's to the right, but keep to the left lane of the exit, and make a U-Turn onto Oakland. Continue on to the stop sign, and turn right to go across the overpass....
From the (Great White) North...
Take 680 south, get off at North Main. Go around the loop and start heading south on Main Street. Take the fork to the right to California, and then turn right onto Ygnacio Valley (just past the Bart Station). The first left will be onto Oakland. Continue on to the stop sign, and turn right to go across the overpass....
…and then
…across the overpass, turn right onto Terrace Road. Continue to the first left (the first one you can actually turn on, there'll be a one way on the left at a stop you should NOT take), which should be Loma Vista. Continue up to the first left again, which should be Cuesta Way. We're at 60 Cuesta Way, the first house on the right after you crest the hill and start back down round the bend. Brown house, red doors.
