RE: dial up sucks (venting)
For years on our 900 acre hunting lease we had to leave the camp area and go to a boundary roadabout 300 yards East to make a cell call. We didn't get reception anywhere on the lease.
Then, three years ago they put a new tower in the area and now we can call each other on our cells from anywhere on the lease. It's a real nice safety feature which we fortunately haven't had to use for any real emergency. All of our calls have been "was that you that shot" or "are you seeing anything" or "hey, I stuck my truck and need a pull" or (the best one) "come help me drag this deer".
