Meeting a friend at a concert?

I've met a ton of internet friends at concerts and it's tons of fun!
First off, designate a place for you and your friend to meet. By the doors or by the merch table usually is a good spot. Make sure wherever you meet is in a very public and open space. You might be 99% sure your internet friend is for real, but it definitely doesn't hurt to take extra precautions just in case. Then, if you both have general admission, you can go into the pit together and hang out. If you have seats that are separated, when the show starts go to your seats, but you could also plan to meet somewhere else after the concert too.
The main thing is to just make sure you are safe.
Have fun!
