Dry box for Washington?

So I see there are a lot of people who use dry boxes. Do you think a drybox is needed for someone living in Washington? It is nothing like Florida or Hawaii XD, but indoors our humidity can range from 45% to 55% (when cooking our vent sucks). Should I be concerned about fungus growing in my equipment?

I use a pelican case with 2 dessicant packs. i live in NC and the % humidity is the 90's during the summer.

I've lived in Washington and owned camera gear for over 35 years and never had an issue with fungus/mold on camera gear. It wouldn't hurt to use a dry bag, but unless you're storing gear (particularly if used in wet conditions and put away damp) in your car trunk, unheated garage, or tool shed, I wouldn't be overly concerned about it.

Provided you are not using your gear in the rain, you should not need to take any extra precautions. Of course if your gear gets wet you will want to make sure to dry it properly.

Humidity goes up here in the winter, but not excessively and then our indoor heating brings the humidity way down indoors.
