We're not leaving till Sept 2025, but have already bought rain jackets, rain pants, waterproof hiking boots, waterproof backpacks, and rain ponchos to cover the backpacks just in case. Rain is the one thing we are expecting. lol. If we catch good weather it'll be a pleasant surprise, but if it's rainy like we expect we'll be prepared.
It's the other stuff I'm not sure about and how do we fit everything into one suitcase and keep it below 50lbs?
