With such short notice i suggest you phone the various group reps from the mag closer to the time. In our planning world we tend to only make the day trip plans within a month of the date. If it is a weekend trip then its usually about 2 months before.
We get out on local day rides about, oh i dont know, every weekend between january & december. There are usually about 4 multi day trips throughout the year, often in Wales.
THOUGH, august is the quietist month as most members commit to more socially acceptable commitments !Gaffa
