Now, I need some thoughts and opinions from people. I consistently have this one spot in my yard where the snow always melts first. In the Summer, grass dies in this same spot. But I can't figure out what might be causing it. So I took a picture and figured I'd throw it out there and see if anyone else has some thoughts. You'll see the big melted spot in the lower-left, while the rest of the yard still has a layer of snow.
I have considered gas line leak - that might explain the dying grass, but I don't think that accounts for melting snow. Besides I don't think the gas line runs exactly under that spot anyway. This picture was taken from the sidewalk, my back to the street, camera facing perpendicular to the street. I hope it's not too dark to see, but the red circle shows where the gas line enters the house.

I presume that the gas line would not run at a diagonal, but rather be a straight shot toward the street to allow for the shortest amount of gas line that would have to be laid. If that's so, then the center of the snow-melty-dead-grass spot is a couple of feet to the left of the gas line.
Heat would explain both melting snow and dead grass, but I can't think of anything that would be there that would generate heat. And I don't see such spots in any of my neighbors' yards.
So, anyone ever seen anything like this? Have any thoughts? Ideas? Speculations? Let me know!

Update June 2007
So now that it's warm again, here's a photo of the dying grass in the same spot as the melty snow that I talked about last winter. Weird huh?
