Years ago in Texas I wrote a simple selenium webdriver script to check on the status of available camp spots in a popular state park and notify me when one became available. Kind of a last ditch effort to camp as people would book months ahead of time but would sometimes cancel their reservation when they realized they can’t make it. I think they’d do it before their small deposit became non-refundable.

The alternative of manually checking every day would have likely resulted in never getting a spot. I was using my skills to hack together a solution for myself in a crappy situation.
