After the Thirty Mile Fire, the New Generation Fire Shelter was put into production. Made by Anchor Industries of Evansville, Ind., it's said to reflect 95 percent of radiant heat. It's fairly compact and lightweight, measuring only 81⁄2 by 51⁄2 by 4 inches and weighing about 5 pounds in its pack ($340-$400; firecache.com). Of course, proper training in the use of the shelter is an absolute must. A good place to start is "The New Generation Fire Shelter," from the National Wildfire Coordinating Group (nwcg.gov/teams/pmswt/pms.htm). --R.J.
