Hey Bunk -
My buddy FRED got his pack stolen this Summer when he was inside a Hostel. It was a huge bummer - luckily he had some additional gear at home that he was able to have shipped to him.
There are going to be numerous occasions on your hike where you are going to be away from your pack. I never hesitated to step away from mine to check out a view or to take care of “business”.
When I was in town however, I would keep it with me as much as I could. If I did have to leave it outside of a restaurant or establishment while I was inside, I ALWAYS took my camera, debit card, ID, journal, etc. Basically those few things that money can’t just “replace”.
Just be smart man. The trail is an awesome place full of awesome people, but you know - there will always be those who are out for themselves, no matter where you are.
Have a blast!
