David, if you're using a PC, and getting a lot of redirects, than there's a good possibility you've got malware on your computer. Sometimes that happens when your computer is part of a "botnet." If that's the case, everything you're doing internet-wise is going through a central "host" that's controlling your computer for their own purposes whenever it's on and you're connected to the internet. (Usually for sending out spam.) If it seems to be "working" (Hard drive light flashing, etc.) yet you're not using it, that's a good sign someone else is.
A good thourough virus check with an anti virus program, plus using Ad Aware and Spybot Search and Destry might help.
The NHRA site works fine for me.
Good luck.
