Track racing is more safe that stunting IMO. The track conditions are known, whereas street conditions change constantly. Plus, you don't have to worry about cagers on the track. As far as skydiving goes, it is very safe, especially for your first time. You will have to either go tandem or static line. Either way you can't really fuck it up. Unless the chute is packed wrong or something. I think one of the recent stats was somewhere in the range of 1 out of 70,000 jumpers will die due to accident. I think it is fun. I have a jumped several times and hope to be free-fall certified soon. Go for it.
