Another half???

So, I'm contemplating training for another half marathon.  The one I am think about is in Dalton, GA on October 15th.  Here are some pros and cons.

Pros:
1. Being on a plan helps me stay motivated to run.
2. I feel really good when I am running consistently.
3. I think I can run a better time since I now know what the distance feels like.
4. With school starting, running gives me a way to relieve some stress.

Cons
1. I don't know how runner friendly our apartment will be in Chattanooga.
2. School will start in August and I don't know if I will be able to keep up with the training.
3. The weather is still really hot here.
4. I would have to start trying now... or yesterday!

I'm going to think over it for the next few days.  Even if I don't train for a half, I will probably start training for a 10k.

Any thoughts???
