Congrats!!! You won't be disappointed with your new snake. They are great animals. And yes, definitely worth waiting til the weather is right to ship. You'll have him around for 20 years or so, which makes a few more days worth it for a healthy animal.
And you have definitely come to the right place for info and questions. Don't be shy, there are a lot of great, knowledgeable people on here who are happy to help out. I just joined recently and have spent hours reading posts and educating myself. I am stoked to have such a wealth of knowledge at my disposal with so many helping hands along the way.
