I don’t think it’s as sketchy a neighborhood as it might seem on Google but with so much gun violence in the city now, nowhere is considered safe anymore. If you’re anxious about finding parking I would probably consider:
1. Avoid going at night and call to find when it’s normally slow so you have a better chance of finding a spot. Hopefully, you can arrange your schedule to accommodate their slow time.
2. It’s an hour drive, so this might not be a good suggestion, but since you said you’d be good after the first visit, maybe just plan a recon visit. Go in the city for a meal, or to grab a few drinks watching a game but make sure you drive around AZN and see what you think. Without the stress of knowing you’ll have to perform you might find it more pleasant. And if you strike gold and there is a parking spot, you could scrap your original plans and pay a visit as a walk-in customer if you’re up to it.
