Battery...

a good ride home last night although there was a fair bit of stopped time...my helmet light died after 40 or so minutes so I think it's time to replace that battery - it's a 3hr one purchased in 2009 so it's had a good run...

the stats:
start temp/humidity: 11.2/66% (apparent temp 8.2)

this morning it was quite fresh for the ride in...
