I have had the same problem recently. Today, when I went to get groceries I put all the goods in the right saddlebag. Problem solved.
Speaking of saddlebags, let me put a plug in here for Leatherlyke. I ordered new locks on August 4th and received them today, August 8th. Dang, that was fast, especially since they advise on the website to wait 3 weeks before shipping. The leatherlykes don't look nearly as good as the corbin's, but they are functional and you can drop the bike on them without damage, I should know, I have done it three times.
