Parking in underground garages. They make me feel boxed in, like my car will be trapped. If I'm not behind the wheel, it's not nearly as big an issue. If it's an above ground parking garage, I'm fine.
Parking in the boonies at the county fair, where I can't get my bearings, so I'm afraid I won't find my car. (It's a REALLY big county fair! There's always people wandering the parking areas looking for cars!)
Hmm... both car-related issues. When I get a therapist, I'll have to discuss it with her!
