I have a few friends that live around the Montpelier area of Bristol... In the summer, a walk from their house down to town can save about 10 minutes by bus in the rush hour...
However, walking through Stokes Croft or waiting for a bus in Montpelier at 21:30 on a winters night in the dark is just asking for trouble... (Something i've had first hand experience of but fortunately the No. 70 turned up just in time to

)
Taxi me thinks... Costs about ^5 to get to the centre or about ^12 direct to
BRI» IIRC▸ (assuming another 89p McDonalds Cup of Tea is not required

) But really
IMHO▸ thats good value if you consider the much, much lower risk of getting mugged/attacked etc...!
