Congrats on the beginning of your journey. Dont worry too much about if you have everything you need, even the best find they forgot something. It is exciting to see a young lady such as yourself start this journey. I wish you the best of luck, and give you this small reminder, dont worry about others or compare yourself to others. Make this journey about you and enjoy the experience of a life time. Congrats and good luck.
Looking forward to following along. Hope you have a great adventure. Please be aware that bear spray is not legal to carry in certain national parks like Yosemite. You will find it is just extra weight. Be careful and have fun.
