What part of Indiana? In Indy, Modern and Premium are two good stores on the south side. They tailor to the web but do have walk-in days. The Reef is in Broadripple. They have gone down hill over the years but appear to be making a comeback. Additionally, there is always Uncle Bill's or PetCo.
Be sure to check our INDMAS. I believe it is still $20 (could be 25) a year for membership which gets you access to website buy/sell area of the forum and monthly meetings. We have a frag swap coming up next month. One of the best around.
Welcome to Indiana!
