Outback outfitters is a decent place for clothing. There's an outlet in Oxford. There is also a decent tack shop in Newark, DE called Bunny Junction. There's also a tack shop not far from Lancaster County in Rising Sun, MD. I can't remember what the name of it is. But I'm sure you can pull it up on www.yellowpages.com
by typing in tack shops and Rising Sun, MD.
BTW...WELCOME to the forum. Lots of good people and good information. I have found it to be very addictive. LOL.
