Games were in short supply across the London & South East Division as frozen pitches caused postponements - but some found novel ways of getting around the problem.
Welwyn's solution was to switch the clash with Ruislip from their Hobbs Way home and head to the artificial surface at Redbourn Lane, home of Harpenden RFC.
Both sides were playing catch-up in terms of fixtures, with Welwyn having one game n hand at the start of play and Ruislip two.
But the switch proved a shrewd decision for the de-facto home side as they romped to a 34-7 success in the Counties One Herts Middlesex encounter.
The sides were both in arrears in their fixtures after the heatwave at the start of the season.
And while the icy and freezing conditions were as far away from that as possible, Welwyn were in a fiery mood and took the game by the scruff of the neck from the off.
Veteran Rob Picken scored on the stroke of half time to give them a comfortable cushion at 19-5, following earlier tries from Ash Dobney and skipper Josh Milton.
Brendon Marume added two conversions.
Welwyn’s scrum was dominant in the second half but stubborn resistance from Ruislip limited their scoring opportunities.
That stalemate was finally broken when Dobney crashed over for a bonus-point try from close quarters, and his second of the game, to extend Welwyn's lead to 24-7.
With only five minutes left on the clock, Welwyn’s pacy backs finally created some space, with Liam Scofield delivering the final pass to Welwyn’s Fijian utility back Makario Ulavuca, who sprinted in to score in the corner.
There was just sufficient time left for Marume to round off an impressive performance in the centre by scoring out wide to take the final score to 34-7.
A 4G pitch was the reason for the only other match in the division taking place.
That allowed Datchworth to travel to Chiswick but there was to be no joy for them as the home side secured a 62-27 win.
The results mean Welwyn stand sixth with six wins and six defeats from their 12 games.
Datchworth are down in 10th but 10 points clear of Enfield Ignatians in the first of the relegation places.
Weather permitting, Welwyn will travel to Finchley on Saturday with Datchworth on the road at Hitchin.
