A couple of items I wish I had more of or thought of.
Chapstick
Record the trip through whatever medium you choose
Journal
Pictures
video, etc.
all three.
Remember that it passes quickly and you might not be back to the “spot” you are at, at that moment. Make sure you stop and really soak it in and enjoy it. The ph will get it and understand.
Lastly. TIA - This is Africa. Little and really big things will happen. Roll with it or let it roll off you back. Do not let any big or small thing ruin your mood or the trip.
Have fun, be safe, good luck.
