If you need directions to the nearest dive shop to Blue Springs, here it is. 17-92 coming from Deland, pass by French Ave (you will see a brown sign indicating that you would turn right to go to Blue Springs). Continue on 17-92 another 2- 2 1/2 miles. Look for a Food Lion sign on the left, and get in the far left lane. That lane turns into a left turn lane turn onto Enterprise Road. Once on Enterprise Road, take a left into the Food Lion parking lot at the first stoplight. Scuba Florida is just pass the Food Lion.
Cynthia at this shop will take good care of you, tell her David of David & Cathryn referred you. Hey, you never know, it might get me a free fill, LOL!
If you need more in depth directions, say from I-4, or the above isn't clear, feel free to post back or PM me, as I live in the area.
