I haven't been to ACT in a while, the last time I was there the trail near the staging area near the town of Niles was closed. haven't been back since.
sounds like the trails fixed now, I'll have to go back.
Actually, only the last maybe 1/2 mile of the trail, where it crosses Mission Blvd. near Niles, had been closed (and it still is, it's going to be finished sometime this year they say) - the remainer of the Alameda Creek trail past Mission Blvd. heading west toward the bay has been open.
I think I know where your nemesis is, as you head west, towards the bay on the flat part of the trail there's a place where the trail curves and then you take a sharp left and imediate uphill. Is that it?
If it's what I think you're talking about then, err, no... I'm glad to say I can do that one. The one I'm talking about is farther south, more towards the Dumbarton. It's near the camping area called Dairy Glen.

Here's a link to the map of Coyote Hills, if you're ever interested in going back there. I really love it there, it's especially beautiful this time of year with all the greenery:

Jo's Nemesis Du Jour is the Meadowlark Trail, which is the gray line just above the words "Coyote Hills Regional Park" on the map. Good grief, according to the map the paved uphill part is only about 0.4 miles. Oh the shame I hope I can made it up it soon, LOL!

So when does the Mondonico arrive?
