Nice to see a new face !
I am in Tucson and do not think it is too late for you to start some tomatoes in cups to be planted out. We are around 2500 elevation, I think, and I would not put the plants out till in March. The season is short, however, because of the high heat we get, so cherry tomatoes do better here then the bigger ones. You would be a bit cooler so maybe the others would do well also. We need to get them to blossom and set fruit before it gets into the 90's. You can always buy tomato plants in six packs to get a feel for what grows well for you.
I have not heard of White Hills, Arizona. Where is that ?
