Do you use tracts or evangelistic booklets (4 Laws, etc.)?

I used to litter rest rooms everywhere with tracts. I still believe they can be useful in certain situations, but I don’t use them nearly as much as I used to. And, although it is a common recreational activity in the theological world to criticize the 4 Spiritual Laws, and know a number of people who were led to Christ visit this simple approach. Several tract publishers are no longer in business. What about you? Your thoughts are appreciated.
