Adventure knows no age limits.

There is a husband and wife team from Minnesota that plans to walk around Lake Superior this summer.  Their story, on the front page of today’s Variety section in the Star Tribune, relates how the 60-somethings plan to start the clockwise, 1800-mile journey in late April and finish in early September.

Notably, they are attached to a couple of causes.  First, they want to inspire older Americans to be active.  Second, they want to collect data in support of research on the health of the lake.

I wonder: what causes could I support during my journey?  Funding for hockey for underprivileged kids?  Lower-48 awareness of Alaska?  Advocacy for entrepreneurship-friendly tax policies?
