As far as I know the only plans I really have for summer is taking care of my daughter and it helps to have a job. I would say I probably won't have any back problems cause I'm so use to my back hurting but I'm only human and I'm sure one of these days it will take a toll on my back. Plus it will just give me a chace to prove a female can do mans job just as good as a man can if not better in some cases.
As mentioned before there are many carrer paths in this trade. I chose to take the commercial path where there is a whole lot more physical stress than in doing residential work. The best of luck to you.
