Thanks Steve,

This reminds me of another question.

Has anyone seen these go 20+ years?

Is there a recommended time for replacement?  If so, is this based on any science or just what feels good?

Our bags are 16 years old but look and work good.  Of course our tires were over 25 years old, looked and worked good but I still replaced those for safety reasons.

Thanks!!!
