Elaine,

I'll try:

No, it doesn't have to be pine... but,

You need to watch your weight. Try to find an available wood that is about the same density as pine, and has about the same strength.

I'd assume that treated lumber is heavier than un-treated lumber... so if you cannot find wood that is comparable in weight to pine, then you should drill a few holes to equal it out.

In a few days (Saturday) we'll have our bridge done, and I'll post the weight.

In the mean time, I suggest that you make an incline that mimicks the angle of this year's bridge, just to see how hard it will be to tow or push things up it.

Besides that, I really feel sorry for you folks in Hawaii. I want you to know that we had a "heat wave" today... 36 degrees! I think that I actually saw the surface of my driveway!

Andy B.
