You said you'd be in the Glendale/Peoria area. Not knowing exactly where you'll be, or where your trip may take you, if you're interested, use these Phoenix PD talkgroups on Simulcast A and/or Simulcast G:

2808 B-2 Black Mtn Precinct
The Black Mtn Precinct sits east of the city of Glendale, and north of the Cactus Park Precinct (roughly north of Bell Rd).
2991 A-9 Cactus Park Precinct
2975 B-9 Cactus Park Precinct
The Cactus Park Precinct is immediately east of the city of Glendale.

The Arizona DPS (Highway Patrol) on the Loop 101 Agua Fria Freeway which runs northerly from I-10 in Phoenix, up through Glendale and Peoria, then turns east through Glendale and Phoenix again to I-17, can be heard on Metro West, 460.300. Metro West also covers I-10 west of the 101 interchange, I-17 north of the 101 interchange, as well as portions of US 60/Grand Ave, which runs diagonally southeast/northwest through the Northwest Valley; AZ 74 Carefree Highway from US 60/Grand Ave in the west to I-17 in the east, running through both far north Peoria and Phoenix; the Loop 303, which while under construction in several stretches, is driveable, and will also eventually connect I-10 with I-17, farther west and north than the 101 (but does run through northern Peoria, south of Carefree Highway). City PD's and the Sheriff's Office also patrol various stretches of the 303.
