Honestly, the bar is very little to get the lifetime pass if you go to a busier park. My wife just had to show the disabled parking pass and they gave it to her without any of the supporting documentation. Was way easier then we expected and hoped she had the right paperwork. I keep my annual pass renewed so I can go locally without her.

Taking up new skills that required little to no thought when my girls were young was the only way I survived mentally on those days you can barely get going due to their sleep/sick patterns. Some days it was slight progress on a long project that allowed me to not feel like I was trapped in Groundhog day getting nothing done.
