Didn't mention the fragmentation grenades inside the trash bin before you cross the bridge or the duffel bag with weapons and ammo next to the statue at the other end of the bridge, nor the fusion core in the mole rat den behind the Red Rocket where you recruit Dogmeat which you'll need at the Museum of Freedom for the power armor without lockpicking or hacking perk to start the mission to clear out Concord. One thing about that power armor, allows you to jump down to the ground level without taking fall damage with a retail store to take cover in front of you, after that clear out the first few raiders with a machete found in the Concord Speakeasy second floor(go there before mission) to not waste ammo, exit the power armor to not waste fusion core battery and go inside the retail store waiting for the deathclaw to kill the raiders then go outside and run back inside the store by suckering it into following you then unload all your ammo into it through the door and windows because it doesn't fit to pass through doors. Alternative is being in a world of pain at the start of the game when deathclaw is much higher level than you and it's best to give it "an express ticket to hell' as Sturges said taking no damage.
On a related note, there is an unmarked location northwest of Bedford Station that's a useful rest stop, a scavenger campsite with a sleeping bag and cooking station that you can find by the music playing over the radio on a table there, it's under a billboard and not hard to find. If it's news to me most likely it's news to others but that article I posted is not "news" to me I have most of the map memorized after over ten years of exploring it.
Another tip is that wherever you see enemies outdoors they will respawn and it's best not to aggro enemies when you can tap VATS button periodically to detect them and circumvent them, memorizing spawn points is a key to Survival Mode and aggroing is not necessary. You can play without taking any damage, there's no permadeath but it makes having to save for anything but the end of a gaming session less immersion breaking.
