Hi,
Check out the thread "How to choose a gymnastics club" at
http://www.gymchat.com/messageboards/viewtopic.php?t=1034 - it gives some good things to think about when choosing a gym. It really depends on what is bad about the gym that would make you decide it is better not to go there, even if you have to drive a lot farther for a good gym - like you wouldn't want to go to a gym where the coaches are inexperienced, where the location is unsafe, where the equipment is unsafe, or where it is 50s in the winter because the gym owners refuse to turn on the heaters, etc. - some things are just unsafe. You can check out the Gym Chat club listings & ratings directory at
http://gymchat.com/listings for clubs in your area; it is the most complete directory for gym clubs in the USA. There are club reviews there, post your own too, it will help others in deciding on a gym.
