Here is a chance for you to turn back the clock and cache like its 2002. To qualify for logging this cache you need to have Found (or own) a minimum Delaware 22 caches that were hidden in 2002 or earlier. You will have send me a list of the caches you are using and the date you found them to demonstrate that you have met the challenge requirement.
Right now there are 26 active Delaware caches to choose from so you have some slack and any past finds of these will count. For the longer time caches they may even be able to use some finds on 2002 or older caches that have been archived.
Why only 22 of the 26 caches? Maybe you dont have someone to sit at the computer to help with the two web cam caches or dont want to do two long involved multi-stage virtural caches or a difficult multi. Or maybe one or two of the oldies get disabled or (I sure hope not) archived and lost for good. If there are not a minimum of 22 active older Delaware caches, the required caches to find for this challenge will be reduced.
So what are your choices for caches to do:

Go back to the end of 2002 when I found my first cache and consider what geocaching was like. Was it the good old days?
There were no micros or shopping center hides.
A small size cache was a 30 cal ammo box instead of the more normal 50 cal ammo box.
Caches took you to interesting places with nice hikes in the woods.
There were no super dificult puzzle caches to fry your brains, in fact there were no puzzle caches at all.
There were no evil hides and if you couldn't find the cache the hint usually told you enough to find the cache.
Some caches took you to very interesting places and didnt even have a log book to find (Virtural caches).
No one was concerned about how many caches they had found.
Then again maybe things were not as great as I remember.
After your first couple of finds you had to drive pretty far since there were only about 30 caches in all of Delaware.
They were all not in great places, in fact one of the earliest was in the middle of a swamp.
One of the multi-caches called Easy Mult was anything but easy!
Older style GPS unit that you had to punch in all the coordinates by hand.
No navigating units or PDA's so you had to print out cache pages and map pages.
