Relatively new to tent camping - I recieved a 3-man dome tent and a couple nice sleeping bags from work (safety award, for every year nobody chops off a finger, we get a $100 or so safety award

So this weekend the wife and I did some camping in Theadore Rosevelt National Park (it's in North Dakota - on the Montana boarder). (Pics coming soon)

And sure enough, it rained one night. In the morning, there was a small puddle in each of my tent corners. Not alot, probably ~ half a cup or so. But annoying - how to best fix this?
