I did the first day of TOMRV this year and really enjoyed it. I didn't do the second day on account of lots of rain (clearly I need to HTFU). Good route, pleasant enough scenery. I will likely do RAGBRAI this year just to see what it's all about. Only problem is the last day of RAGBRAI always coincides with my favorite running event (Bix 7).
