Travel trailer storage near Winchester Virginia

My wife and I have been wintering at an Encore Park near Venice Florida with our 27' TT. We will be leaving Rochester, NY shortly after Christmas. We would like to make an October trip to the Winchester VA. area and leave the TT in storage there until we head south in December. I would prefer indoor storage but will also consider outdoor secure storage. Does anybody have suggestions for a storage location within 50 miles of Winchester? Thanks for your help.
