This is an easy one. No mental tricks needed. However, muggles are everywhere so put on your best stealth/incognito presentation. If you don't know the stealth look, mental tricks just may be needed.
Camo container with a little room for swag. Needs to be replaced carefully. Try to cover with some brush if possible. Bring your own pen please. Only tiny trinkets may fit. Beware of the thorny trees around you. DONT just grab a branch. those are thorns. Despite thorns this is a pretty easy grab just need to bend down to grab it. no significant bushwacking needed. just off the lot. This is a better wintertime find.
