Wondering about the heat

We went to the Bird Preserve Monday and it was a lovely 70 degrees. Maybe a bit warmer. The sun was hot and the boys were actually complaining that they were "melting". I can't help but wonder how things will be in a few months when it's 100! I really am not looking forward to it. I get so worn out by just sitting out in the sun or even in the shade on playground days. I don't know how much I'll be able to do it once it starts with the hot nonsense. I don't want to wear myself out and then spend 3 days recovering. Perhaps I'll be ok until May. We'll see how it goes and how my body is dealing with the heat. Hopefully I can find a way for the backyard to be more attractive and playful. I don't know about a pool this year. I honestly will not be able to take care of it and that's just too much to ask Danny to do. Hmmm, maybe a playground set?
