Second Leg?

[1sttimelongtime]

Here's what is probably a dumb question -

When Mick in the meet n greet that was discussed on another thread mentioned a second leg to this tour, what does that entail? Will he hit the same areas of the country, just different arenas and later in the year or does it mean they are off to other countries?

I never paid attention to this stuff when I was going to Metallica concerts, if they were around, I saw them. End of story. But I'm a little more interested now! Can anyone tell me what this second leg is likely to consist of?

Thanks!
