Alicia, welcome to our forum, you have found this place that will help you to learn about your bees, we have beekeepers that have kept bees their entire lives (well, since they were old enough to walk, at least) to many new beekeepers. You are wise to listen to those that tell you to keep at least 2 colonies, the reasons have been told.
You will love to spend time here and learn, it is the best tool for learning, lots of ideas.
I love the picture of Mt. Ranier in your avitar, simply beautiful and breathtaking. A little ways from my home, I can see clearly Mt. Baker. To see these mountains from a distance as such, is the most beautiful thing to see. Lovely.
About your family growing giant pumpkins. When you get the bees, holy smokers!!! You ain't seen nothin' yet. With the pollination that the bees will provide to these pumpkins, they will be even more gianter!!! Yeah!!! They are gonna have some alien sized pumpkins, just wait and see.....have a wonderful and beautiful day, love our life we're all livin'. Cindi
