The only show I know I'll be going to is SHEL when they hit the Springs (no date yet, but they play here every year). I took my wife last year and she was blown away. My in-laws bought us tickets for the Broadway series that plays in the Springs this year (Cinderella, Sound of Music, Evita, Les Miserables) so we get to see all four of those shows (already been to two of them). Not concerts by any stretch of the imagination, but still very high quality performances.
Aside from that.....the discretionary cash spending is really limited until we are out of debt. Which hopefully will be by the end of 2019. Maybe sooner if I can get a new job this year. Though if anything 'must see' falls into our laps I will likely splurge.
