Slugging is GREAT!!!!!!!!!!!!!!!!!!!!!!!! I live in Houston and when I worked downtown I did it frequently! When a bus ride costs 3.00 each way and takes 15-30 minutes longer you better bet I will take advantage of slugging. Oftentimes if the weather was bad the driver would drop me off right in front of my building! Most of the time I had friendly interesting conversations with professional people from all different walks of life. Not once did I feel uncomfortable or creeped out. I know it seems strange, but when you see it in action and participate in it, it becomes a matter of routine, just like riding the bus. In fact I would often ride with the same people, so safety was never a problem. I no longer work downtown so I cannot take advantage of slugging, but now that DH works close to downtown he picks people up every day so he can get to work. It is a HUGE time saver! He saves at least 30 minutes every day by doing it.
I think freecycling is tough to get. Giving is easier, but even that is tough, because trying to coordinate with flaky people who never show up when they say they will is just frustrating. I did it for a while, but here in Houston there a million takers for one item so it's just not worth the hassle for me. Time is money too. I'd rather do thrift stores and garage sales.
