Paul,
It might be easier to say just how far you are willing to go - maybe an hour
Two perhaps ???
If we say that as you're towing a caravan you're going to be
blocking the roads and generally getting in the way of sane motorists travelling slowly and not likely to get much further than 36 miles in an hour (or maybe even that far in two hours
) your travel radius from Montrose is then sorted
Would you prefer river or loch
