Is 20 minutes the standard answer to " how long does it take to walk into town"?. We have asked or just been told on many sites that it is just a 20 minute walk into town, to the shop etc. The latest one turned out to be 2.3 miles and approx 44 mintes. The best one was in Cornwall. About 4 miles and just over an hour......... Don't mind a walk but whay do they all say 20 minutes???????
