This morning, I mentally kicked myself as I stood shivering outside a barn in Adams County while out on a story: Why didn't I bring a jacket?

It's not like I don't have plenty of jackets. It's just that when it comes to gear, I always bring something when I don't need it and don't have it when I do.

I bought an underwater camera for snorkeling on my last vacation, but the first trip -- when I had the camera -- was a dud. Nothing worth photographing. The next time out, I marveled at purple coral and electric blue fish and gritted my teeth. No camera.

It's the same thing when I go for a day hike with friends. I don't want to pack too much because then I have to lug it around all day. But the one time I don't bring enough water or opt out of the first-aid kit, I know I'll be sorry.

I guess it's just a trial-and-error thing. Or a matter of drinking some coffee before I leave in the morning so the brain is going when I pack.

I like simplicity. I want to travel light. But I also want to be prepared.

Anyone have any suggestions? Tips?

As you can see, I need them.
