This was posted on another site I go to. I have copied what they have posted as I feel it is great for each of us to voice our opinion:
The OpenCongress website lets you track what's going on in congress - they also have an "Oppose/Support" vote area for different bills.
Here's the link for S373 (the Python ban). It only takes a moment to create an account and voice your opinion!
