I Just did the same search. This is the first time i have ever heard of the wally walk. I figured most experiences were just as yours was. Although i am sure someone has a funny one.
If you have not carried before you will be nervous (I think it was worse when I did it because we could not even print), You will be wondering who is watching, can they see, am I printing...., When you get the comfortable holster and carry even a short time you will get to where you don't even think about it.
The trick is to not look nervous even though you are.
good luck to ya and congrats on getting your LTC.
