Yes I agree something for the winter is required, if only to help fend off the looming decorating jobs that err indoors will suggest if she senses you have nothing to do!
My solution to this has been off road trials riding & there are classes for old bikes so it need not be to expensive either, there are practice venues arround that make for a good Saturday afternoon & competition meetings that I do when I can. Our local pre 65 club is friendly & we have a good banter, unlike the modern boys that are very competitive with no friendly buzz at the meetings and they seem to enjoy wearing lycra.
The bikes are not road going so a trailer or bikerack is also required, this passtime also carries little danger infact is a health benifit running up & down large hills when walking the course before the ride suits me sir..ohh!
