If all they need is shelter from lightning, it's really not expensive. Go look at the steel buildings they have on farms. They could throw one of those up in a month and with a couple hundred grand.
That's why it's annoying to see practices canceled due to lightning after all these years.
Now, it wouldn't be air conditioned, and it would be spartan as ****.
Since almost everybody on this site canceled their 100$ subscriptions to grassy all the money should now be funneled over to a donation that goes towards building an indoor facility.
