Default Density Altitude (DA)

I found a DA caluclator at:

http://rshelq.home.sprynet.com/calc_da.htm

I need to know where I can find the altitude and the dew point so I can calculate the DA. Anyone know of a website with that info. I tried weather.com but they didn't have it.

ok, the DA is 2400'. Is this high/low? I'm guessing it's not very good since it's pretty damned humid outside.

2400 flat out sucks.Thats a very high DA. Most people wont even post times they ran in that high of a #. Expect the car to be very slow compared to a 0 DA or any negative DA.

2400 isn't a great DA, but considering you are in Michigan, and it is July, that really isn't too bad.
