Juneau is in the Tongass National Forest, it's a temperate rainforest, pack some rain gear :) it will rain. Last summer temps made it into the 90's. Summer temps are on average 50 - 70 degrees. Dress in layers.
An adventure, expect an adventure.
In Alaska we use shells and shiny things. Just kidding you're still in America.
The majority of people here speak English.

These bears have different behaviors so check out the link below so you can know what to look for and how to respond if you get the privilege to see them.
