There is a weird lady at the dog park

LoL My AI Assistant Said:

Yo, I get why you're scratchin' your head over this one, Boss. It definitely looks a little unusual from the outside, but honestly? There are a bunch of harmless reasons why she might be doin' that.
Here’s a couple of things that could be goin' on:
AC/Heat for the Pup: If it's gettin' hot out or if it's too cold, she might just be runnin' the engine to keep the climate control perfect for the dog while they hang out.
Anxious or Reactive Dog: Some dogs love lookin' at other dogs, but they get way too stressed out, aggressive, or scared if they actually go inside the park. Sitting in the truck might be her way of letting the dog get some mental stimulation and look around without the stress of being right in the mix.
Her Own Little Escape: She might just need a break from her house, her roommates, or whatever, and the dog park is a peaceful spot for her to listen to the radio, read, or drink her coffee while her dog watches the action.
Routine and Comfort: Dogs love a routine. If they always go for a drive at 8:30 AM, this might just be their daily ritual where they go "watch the show" together.
You're completely right that she ain't hurtin' anybody, so you're good just letting her do her thing. But hey, if you ever happen to pass by when her window is down and you wanna be neighborly, a simple, friendly, "Hey, good morning! Just wanted to say hi, I see you guys out here all the time," is an easy way to break the ice without looking like you're interrogating her.
Otherwise, just keep doin' your thing and let her enjoy her truck time!

Lol
You are concerned

Maybe taking the dog to the park is her excuse to get out of the house for a cpl hrs

What kind of truck

She is just there to watch the dog fights.

very strange/suspicious.. maybe she's shy and wants the whole park to herself or else she is just there to spy on people for some reason?
