@YahooCare It is unacceptable that when someone hacks your accounts and resets all security data (password/phone) we can no longer use your email. I think we have the right to see what data you have got from us - our emails. Help!!!

Pedaling into 30 mph Headwind and rain hard. But beer in a pub with a fire tastes better after. #tanhillinn

@gawnee yes and no. Have you lost the knitting pattern? Enjoyed siring on my wife's love gift. Not so much the sore ass.

[David Cohen @cycleDAC]

Raining and I have no plunger for my portable cafetiere. Bad start. Grumpy. Damn +cyclingYorkshire

Posh new bike worth a motor in the back wheel. Goes faster. But no knitted saddle. Mary did not deliver this time

[David Cohen @cycleDAC]

Shared hotel room. Four cyclists. Live music. Twenty more cyclists still drinking in the bar. Big hills tomorrow. Expecting some slowness

[David Cohen @cycleDAC]

Arrived in Yorkshire. Whitby lovely
Whale bone arch a bit small. Camera broken. Pedaling tomorrow

[David Cohen @cycleDAC]
