Can anyone name (other than missing out on sleep) any DISadvantages to getting to your stand REALLY early (1.5 hours before shooting light)?

In '06 I saw what I thought was the buck I ended up taking that December run through a pasture (right behind my stand) in the moonlight. Germ said it once......he looked like he was late getting home and he was in a hurry. At least I knew I was close to being in the right PLACE....AND...if I'd been a bit later....maybe he'd have busted me going in.

Last year....I was in a tree when the 8 pointer I would take 4 days later came by me in the darkness.....just sauntering along. he actually stood about 5 yds from the base of my tree for about 5 minutes, before walking on away. I had him at less than 10yds this next morning same tree)...but had no shot He stopped while chasing a doe...but was quartering-to, hard). I shot him 3 days later, when I moved about 40 yds up to where I'd seen him coming from in both prior instances.

I keep thinking if I'd been later getting to my stand all those times....maybe I would've gotten "caught".

Can anyone give me a good reason why we don't go in earlier (as a whole).....other than..."I don't need to" (which is a perfectly legitimate answer, BTW)?
