Ideas to work on short game during WINTER

[Travis Robinson]

I live in Wisconsin and they can sometimes have unforgiving 4-5 month winters here.  The short game is so hard to work on and losing feel is INEVITABLE.  I do have a homemade indoor driving range which is pretty awesome so I still swing quite a bit but I'm more worried about my touch and feel of my short game pitch shots, low chips, chips with spin, lag putting, short putts, ALL OF IT.  How do you guys practice your short game especially during the winter months?

There's just nothing at all that truly gives you a good feel of your short game practice than actually practicing on a real green.
