Explorer Cave

I was looking for ideas for a venue I was putting together and grabbed this as hey for 10L what can go wrong? Its not what I was looking for but its a nice build anyway, pretty well put together using an interesting mix of prim params with nary a sculpt in sight , and yes its a cave. I like it.

The invisible walls stay after you pick the cave up leaving you with barriers in your space, you can stand in mid air and walk into invisible walls that you can't see with see transparent or click on to pick up. I would pass on this product.
