I have made more than one blank trip - I had to turn around and go home. The first time was the 4th of July, and the second time was on a Saturday at 8am. A simple 'hours of business' sign would be considerate of people's time.
The company, owned by a couple dedicated to the personal fitness of their clients, has been in business for over 15 years. They are now participating members of "Silver Sneakers". They have many "mature" clients who are pushing back time by getting fit. They make it fun.
If you are eligible for, "Silver Sneakers" why not come by and see for yourself. It will cost nothing and you will definitely see results.
