@The-red-centaur when I was manic I would be up walking at 3am when the roads were quiet and all I could hear was my breathing. I had one or two occasions where it could have been dangerous but all in all it was fine and like you it is my favourite time to walk. I will head out at 5 today which is a good time still early enough to be dark and yet is not as edgy as 1 or 3am.
