I went to MACNA in DC in 2015 (I live near Philly so it was easy) and I thought it was very good and a great experience. It was quite busy and Julian Sprung spoke to a packed room. Twice. I think they are running into finding speakers that will draw a crowd (Julian certainly did) along with some still COVID-related travel fears. I was going to go to Pittsburgh this year (I didn't go to Milwaukee last year) because it was a reasonable distance and Pittsburgh is a fun city. Oh well. I'm hoping it will still be Pittsburgh in 2024. I will typically go if the distance is reasonable, which is probably another issue they are having with attendance. Also, hotel, air, rental car and gas prices are a bit insane right now, so on top of the vendor booth fees, you have to pay even more for travel than previous years, as Opus mentioned.
