Welcome to the forum. All the previous comments on your post are accurate and true.
Please feel free to exercise any desire you have to shop, dine, car wash, hike, garden, jog ,bike ride etc. while wearing any handgun or handguns of your choice here in Alabama. You won't feel comfortable doing so until you get your feet wet and just do it.
Enjoy the freedom and enjoyment of shopping for different holsters to compliment your chosen attire for the day.
The way women have for years tried to match shoes and purses, we now can match shoes, holsters, belts, ammo pouches etc. Can get a bit expensive, but the more you look all together, the better you will feel about yourself and the less likely you will even encounter a question. You might very well get a compliment from one of us savvy aficionados of guns and their accessories.
Bottom line is, you are in the right by open carrying in Alabama. So carry with confidence. Confidence and self assuredness can be seen and felt from a hundred yards away. So can politeness and a smile. Don't forget to use both.
