Think about the way home
Keep a towel or a suitable place for damp kit ready where it is useful. The trip back through the door is part of the outing too.
Follow the item instructions
Different straps, fastenings, prints and bags need different care. Follow the label on the exact item rather than assuming everything can be washed in the same way.
Reset the walking kit
Refill the things you used, empty the pockets that need emptying and put your next list back where you will see it. One less thing to remember at walk time.
