I am looking into getting camping equipment and doing so long term hiking. Haven't been camping in years. How would test my equipment if I live in the city? I would be hiking solo across the USA, How much should I need for such an endeavor?
I live in the city; to prepare for my Sierra backpacking trips I jam all my gear in my pack and take off walking, increasing distance as my endurance increases. I stop and eat lunch from my pack, using the actual gear. I pitch my tent in the yard at home when I get back (you can do this indoors) and sleep in it. I make dinner using my stove (careful with this indoors) and eating actual dehydrated meals.
This helps me me find and fix all types of issues with my gear (pack, how I pack it, ease of use, meals I like, etc.)
Most importantly it helps me determine which things I really don't need to bring, to save on weight.
