Lettuce still producing

I planted lettuce and carrots on November 27th. We've been harvesting for the past few weeks and have been enjoying both the "rouge d'hiver" and the "amish deer tongue." Both have been tasty and good producers.

I planted the carrots on November 27th also. I should have thinned them more. We've harvested some fine-looking specimens, but some have been too crowded and a bit stunted. Still, they have a pleasant taste and the greens are pretty.
