I agree with Tom.  In fact, I wrote a letter to the editor about just that when some people moved into a new community near here and then complained because they could hear dove hunters in dove season and just KNEW that people were inevitably injured due to hunters and were writing to the paper about it.  I wrote and suggested that, before trying to put a stop to something that had been going on for generations in that area before they moved in, they check the records and statistics on injuries to non-hunters due to hunting in that county up until then.  That pretty much ended that quest to turn where they moved to into where they'd moved from (a common failing in people relocating to a new place to get away from the old place). 

And, Tom, that reminds me of the people who built a house with picture windows overlooking Campbell's Hole up Barton Creek (a popular skinnydipping location since - well, pretty much since people have been in this area) and then complained about people skinnydipping in Campbell's Hole.  They didn't get a whole lot of sympathy on that one, either. 

I haven't been icefishing, but it sounds like fun!  I have SEEN people ice fishing on rivers in the Northeast and then gone back and seen that same river raging with spring thaw and wondered how on earth it managed to freeze hard enough to hold those big trucks out there on the ice.  It just is not intuitively obvious, no, sir, not to me! ;-)

If you start at Barton Springs and hike back up Barton Creek into the Greenbelt, it's up there a ways (about a mile).  I haven't been in years - when all the development over the Greenbelt started, it stopped being a welcome nature etreat from the hurly burly and became just another place in the city, for me. 

Remember, it gets HOT here in the summer.  And people have been trying to cool off for a very long time - like I said, since people arrived in this area!
