Welcome, Phil. Glad you found us. You'll find lots of message threads here about initial experiences in public. People in the U.S. are mostly OK with kilts but curious. You'll discover lots of responses here to the questions you'll be asked, especially "The Question".

The black UK is great - comfortable and goes well with anything. Wool tartans aren't necessarily everyones choice.

And congratulations on reaching the age of 50. You'll find yourself caring less about others opinions since you're now of an age to offer your own. (I myself am aspiring to the exalted title of "curmudgeon".)

Keep us posted on your adventures!
