Closing season mistakes to avoid

Official starter thread from Avenblu Team.

Closing usually goes smoother when you avoid a few predictable misses:
- Waiting until the water already looks unstable
- Skipping a final test and cleanup pass
- Leaving equipment notes unwritten for spring
- Forgetting where supplies and fittings were stored
- Assuming last year’s approach still fits this year’s weather or setup
