They are easy to find. Take the 10 freeway East and exit at Azusa (next to the Hummer dealer). Go south a little and make a right on E. Garvey Ave then follow it through a neighborhood and around a few curves. The 1st T-bolt is located on a small hill at the corner of Lark Ellen and Garvey
As for the second one, you can back track your way to the freeway and go further east to Citrus (I think thats the next exit after Azusa). Go south past the Unocal 76 station; the siren is located next to the creek channel.
I've heard on the old board but haven't checked that Huntington Beach has some powered T-bolts for Tsunami warnings. Last time I checked the City's web site, they said that some of the sirens were located at their fire stations. See if you can get a camera or recorder and be there at the
last Friday of the month and get ready for 12 noon.
If you can make it to Brea as well, a former member on the old board also mentioned a T-bolt 1003 on a fire station on Berry street. Take the 57 south to Lambert and go west to Berry then turn north.[/u]
