    I make...

    Yeah, this is definitely a component of a sure solution. The problem is that the lo-jack branded solution is too expensive, and too large.

    No, it's not enough to attempt, particularly if you know that the measure is ineffective. A completely ineffective measure really is not "something."

    No, showers are not readily available at my destination, and I guess this is a big part of the problem.
