Then they opened the outdoor winery-type ampitheater at George, Washington, very near where I went to college...

All my buddies and me started buying season tickets for the whole season, which means we saw everything.... Rod Stewart to Robert Cray to Journey - Probably 10 shows a year.
We bought six seats between us, right down in front for the whole season... third row of reserved seating, and it was so nice to be so close without being mushed. They set up lawn chairs for us to sit on, and in the early years, you could bring in wine from the winery, though they don't allow alcohol now. But still you can bring in sandwiches and snacks, it is a wonderful way to see a show.
We bought those season tickets for 5-6 years... So I have seen a lot of concerts by popular bands, some that I would not have seen otherwise and was impressed with in person. Like Rod Stewart. Never really a fan of his, but liked a few songs, he was a fabulous live performer. And Billy Joel, of course, is made for performing live.
We had more opportunities to do that when we lived in DC. In the summer there's an outdoor military concert somewhere just about every night of the week. We also liked to go to Wolf Trap. Heard James Galway there and saw the revival production of Jesus Christ Superstar.
We're going Thursday night to see an outdoor performance of Into the Woods.
