The last I remember, I think the min was $300. (I think that’s OK to say) As you might imagine that would get you the very minimum in terms of activity. Other than that it’s all over the map, and depends on all kinds of variables. Even if I told you what I had spent an a particular occasion, it probably wouldn’t apply to your situation. There is, of course, no maximum. Sorry I don’t a more satisfying answer for you.
