I am pretty sure US Equestrian isn't going to surprise us with new tests, the current ones are good through November of 2018, so it's simply up to Speedy to stay sound and healthy.
As I was looking over the shows that start the 2018 season, which begins in October, I saw two different shows that looked great for first timers. The first is in Fresno. It's a two-day show with Saturday's event being a schooling show (cheap!), and Sunday's classes are USDF-rated. I think this is a clever show set up. If we make it, Speedy and I will have one day to dip our toes into Second Level before we let it all hang out at the rated show on Sunday.
The second option is at Hansen Dam in November. It's also a two-day event, but on Saturday, riders get to do a Ride-a-Test twice, and then on Sunday, there's a schooling show. This option would be cheaper with a lot less stress.
I don't know yet which one I'll do. Heck, I might even do them both!
