In late spring I purchased an DFW EagleGolf Card. My home course Fossil Creek Golf Club in Fort Worth, Texas is owned/operated by EagleGolf and they offer this great card each year. You purchase the card for a one time fee and it allows you to play free rounds on each of 9 local courses they operate -- any day, any time. Really a great deal and good way to try some different courses and layouts. In addition, the card provides a 20% discount on rounds at other times and you earn points toward free rounds each time you golf at one of the courses.
Now I am also a Player Development Program member at Fossil Creek and I think it is a great deal as well. It provides free range balls, cheap twilight rates at 2:00pm everyday ($20), and free clinics offered twice a week with the golf pro, and a discount at the pro shop. I play quite a bit at Fossil Creek and love the course with its variety of holes, and the folks who work there know me and are helpful when I want to book a tee time. The starters are great guys and know me well enough now to place me with a variety of groups.
