The scrolling behavior has changed on the iPad compared to the iPod Touch..... if you go to this page:
http://www.geocaching.com/map/default.aspx?lat=30.507617&lon=-97.829567
The embedded map can be be panned/scrolled with one finger or enlarged/reduced with two fingers when on the iPod Touch, but on the iPad, it merely enlarges/reduces the whole page. I had the guy who did Atomic Web browser look into it, and he says Apple changed something in the web browser class that causes this to happen, so we are stuck with it.
