i have been to chennai,hyderabad,mumbai and no iam in bangalore.....yes, there are lot of infrastructure difficulties in bangalore......but the fact is that actually bangalore is an small city and you can walk to nearby places.....but people prefer two-wheelers and cars and that makes traffic all the more difficult......without doubt bangalore is the best metro to walk.....the sideways and footpaths are surprisingly cleaner and greener than other metros.....iam beginning to enjoy walking on bangalore footpaths and parks.....they were well laid.....a walkers paradise......never saw such thing in other metros .......and another thing i liked about bangalore is rain itself.....i always fear walking out in rain in chennai or hyderabad or mumbai without umberalla or raincoat because i usually get fever if i go in rain......but surprisingluy in bangalore rain i was wetted several times in the rain without umberalla or rain coat...even then i dont get any fever not even cold or cough......now iam enjoying walking in bangalore rain without umberalla or rain coat.....it is beautiful experience which i cannot get in other metros.......
