What to Pack for a Trip

How many times have you made a mental list of the items to bring for the list? I find myself doing it everytime I'm going for my travels. So I'm going to make 1 & bookmark this page for myself:

Personal Items:
Clothes - jackets, shirts, bottoms, underwear
Shoes - sandals, shoes, trekking shoes
Toothbrush / toothpaste / toiletries
Passport / Visa (as in for entry to a country or credit card)

Maps / journal

For the outdoors:
Raincoat / umbrella


For Birdwatchers:
binoculars / fieldscope
trekking boots /
camera
