Just going to point out that bard might be an exception for how he should spend his pre-1:30, as his map location influences the initial chime locations (in particular, he should probably be hanging out between the two bot turrets).
For everyone else, people really ouaght to be at the various jungle entrances keeping an eye out for invades. I probably won't blame anyone for not wanting to ward (as I understand most laners want to keep their trinket to protect them for early ganks), and I understand if you don't want to poke your head into the enemy jg for fear of getting murdered, but there's literally no harm in watching the jg entrances until creeps reach your lane.
