Good tip that. Or, don’t be in a rush to get your tent up if it’s raining. Go somewhere and sit it out. It’s a lot more pleasant.Backpackers advice ... make sure you can get to the tent without unpacking anything else, it might just be pissing down!
We generally rock up to a campsite and get chairs and stove out and have a brew and or a beer to relax and chill for half an hour or so. Then put the tent up. Irritability tolerances are a lot higher this way.
