ok let me give you a little insight into the problem.
Yes the roads round here are now clear, mail is moving around BUT and this is the big problem, we still cannot get out on delivery in many towns because the pavements are covered with compacted snow and with today's rain on top they are are very slippery, together with the idiots that have cleared their drives and just thrown the snow onto the pavements blocking them even more. We can't use bicycles because it really is just too risky.
Most delivery offices are more then happy for people to go in and collect their mail, in ours we are spreading the word because we have mountains of the stuff that we simply can't get out, we did try yesterday after the further heavy snow fall, couldn't get the vans out so we went out in pairs trying to clear the town rounds on foot whilst the fresh snow gave some grip under foot. Rural deliveries are fairing much better simply because it is mainly driving on roads and walking up drives etc.
Ask yourselves how many of you would enjoy trudging around for hours in the conditions out there at the moment, just try walking on those icy for a couple of hours yourselves, it really is no fun,
