I don't know that you are invisible, but when I saw your post I reflected back on the 14 years that I have now been coming to San Pedro and how the Wish Lists have evolved over time. I think one of the reason that you are not getting inundated with requests is that so much more is available to us than past years. I wouldn't change all my mule activities because I have made some unbelievable friends through the things that I have brought down for "strangers" over the years. Now it is mainly bribes, not needs.
Come enjoy yourself and if you want to bring something, look at Saga's list or school supplies for one of the schools. You could bring some hand warmers because it is cold here, just kidding.
