I've read lots of "how ____ is too ____?" but never this one.

I get off work at 4:30. I drive home, it's 4:50. I can't take my bow to work because of... well, I just cant. Anyway, I get to where I hunt and it's now 5pm at best. I change into my hunting clothes... it's 10 after. I get to my tree and attach my climber, get settled in and pull up my bow. At this point it's pushing the bottom of the hour... and sunset.

Is it worth it for me to try hunting after work? I can't leave early without taking vacation, and I can only do that in 4 hr increments... when 2 hrs would be perfect! I only have limited vacation time... what do I do?
