Ruth - you are more than welcome - however:
I only have a 21yr old 12.2 Exmoor pony (still fit as a fiddle tho!)
and a 13.2 palomino Welsh sec C stallion, also getting on a bit, aged 17 - also very very spriteley
Had to cut back on numbers, due to desk driving now - and also my back.
Horses on the roads - you guys stop & ask the riders you meet - as you would be suprised at the answers you get.
Not one of the people I know likes riding on the roads - they only use them as a means to get to the next field/comon/heath/bridleway (those bridleways that havent been turned into a mudbath by hooligan bikers:P ).
If I had to go on the roads, it was to get a horse fit by walking it on a level surface & then only where possible on quiet roads. I hated the roadwork - its soooo boring, and also dangerous too.
