Over-Packer Problems

As hard as it is to believe, I am an over-packer.  I know.  ...sigh...
I'm a very sensitive being, so I don't want to be uncomfortable.  
Couple that with Colorado's '4 seasons in 1 day' weather, and it's a recipe for disaster.

The camping season is upon us and our son's 3rd grade class is doing an overnight trip to Sand Dunes National Park this weekend...just me and the boy are going, so you'd think we'd have very minimal stuff (we're only staying one night)...wrong.  

rain jackets
hiking boots 
warm weather clothes
cool weather clothes
food
water
tent
sleeping bags
sleeping pad 
hats (sun & beanies)
gloves
headlamps
camping chairs
kite
hula hoop
sled (for the dunes)

Ok, obviously this is not a backpacking type of camping trip.  
And yes, I know a sled, kite, and hula hoop are NOT necessities for this trip.  
But they'll make it more fun :)

1 adult, 1 kid, 1 night
(the cooler & Camelbak aren't even in the picture!)

I'm pretty proud of myself for downsizing our huge bag of clothing to one small(ish) bookbag.  I realized that we probably won't change clothes if we're only going for one night, so I wiped out half of our clothing.  (Because I have a small 'emergency clothing' bag to leave in the car...ah!  I know, I really do have a problem!)

Clothing is where I struggle when it comes to packing--and I don't even own that many pieces of clothing!  Same with shoes--it's not that I own a lot, just have different 'types' for different Colorado activities :)

If you're going for more than a couple of days and you can wash and re-wear your clothing, that can help you to not over-pack in this area.  And if you can bring yourself to only wear one pair of footwear, obviously that saves space in your luggage.

Another area where over-packing tends to happen is with kid 'stuff.'  Toys, clothes, food, etc.  (talk to my husband about this one!)  Camping is perfect for reducing kid toys--nature has plenty!  For the ride in the car, we usually have drawing supplies and books...for the most part, that entertains our 9 year old and 4 year old.

Ultimately, I just have to suck it up and learn to deal with being uncomfortable.
I'm working on it.
Slowly.

How do you do when packing for a trip?  
Are you an over-packer, under-packer, or just right?
