We had a freak frost here around May 4th (our last frost date here is April 22nd). The frost hit only a small spot in the yard where I had some tomatos planted using the lasagna gardening method with cardboard and straw. I had to use my back-up plants to replant but this Chinese Velvet tomato for which I had no back-up. Luckily it survived and I can use it in my tomato breeding projects. Always have a back-up plan!
