Avoiding those pesky hot-air balloon injuries!

 Rabies incidents from bats; not as much. During the past 50 years, only 48 U.S. residents, according to open records, contracted rabies from bats; that’s less than one per year. That’s less than the number of hot-air balloon injuries in the entire country during the same time period! (for comparison: in 2001 alone, 15,989 people contracted TB).
 Nationally, less than half of one percent of bats have rabies. Bats aren’t rabies vectors anyway (which is an animal that can transmit the disease without contracting it), and almost always die from it before infecting anyone.
Xeriscaping is not just rocks and cactus     In an effort to be ecological, some homeowners have replaced lawns with large patches of gravel.  All this does is create even more heat, which we don’t need in Texas. Good intent, but WRONG. Gravel and rocks tend to heat up the area including the soil. In turn, this actually increases water and energy use since water now evaporates faster, and the well-intentioned owner uses air conditioners more.
The increased heat activates dormant weed seeds beneath the gravel. It quickly becomes riddled with weeds and spotty grass clumps (which break through to the sunlight), becoming a big maintenance problem.
Most species of cacti don’t do well in north Texas, anyway.  Ground covers and tall, prairie grasses are far better Xeriscaping tools, and are much more ecological. They’re better for birds too. I have a list of good “birdscape” plants (that grow here with minimal effort), I’d be glad to share with you.
