Let's just say somewhere in my past I had some huge sheets of graph paper and I created a 6 level dungeon lair .... any suggestions on the best way to get that into a digital format that would be worth anything?

I don't have a scanner (well I do but I'm missing a power converter for it somehow) and even if I did it is nowhere near big enough.

Anyone tried using a digital camera for this type of thing?

I'd love to get these sheets into my computer and work them over a bit.
