Yes... drive around blindly is exactly what exploring means.
I've lived in my neighborhood for 2 years. I know more sites, more landmarks, more "interesting" places than my neighbor who's been here for 9 years. Why? because on my days off... i drive around. I explore. I look and see what stores, what shops, what sights are in the area.
If you "rarely have time to get lost on purpose" .. you're either a workaholic who never takes vacations... or an idiot.
Ok, it's not so much that I don't know how to get around.... It's more that I know my neighborhood. I know my city. I know cities an hour away better than some others. I can navigate LA which is 6 hours away to get me to certain places and certain friends' apartments even though I've probably only driven around in LA 4-5 times.
I'm good with directions.
But last weekend I went to 2 Sport Authorities before I asked them to call and check inventory and I ended up having to go 20 min away to the further away one. I didn't know that area as well. I had to use the GPS.
Yes I can get to my local Safeway, and like the other 5 Safeways I know, or my local Frys electronics, and the backup one, but what about the backup backup backup one that a friend took me to once 8 years ago? If I'm not paying attention that moment, I might not know where to go. GPS helps.
I tend to know places well that if I go once or twice it's already etched into my head even if it's a city I barely know. However, it's the FIRST time that's tricky.
Or on Black Friday, I know the 3 ways to my mall, but that's front side. What if I exited 1 exit early (which I did)... now how do I get to the mall from the back side? GPS helped.
