Problem in my area is finding the space to do an indoor Putting league, few areas with building space big enough that is open to public. Could use some of parents area at store greenhouse they own but, that gets filled in late February to early March. I can think of a few others but they are not the best area, just a long tunnel with limited space left to right to putt. Pierre South Dakota the town across the river has a few place you could do this but they are expensive to rent. The best place to do this closed down last year. I think a part of the YMCA might work, they never use that part of the building anyhow. They are older racket ball courts that never get used and if we need to have more space there is a hallway to the courts for putting in too that is about 70 feet long.
