I drive a Ford Focus estate so I guess middle ground on the fuel ecconomy stakes, I have swept most of the caches close to home since moving here (Ipswich area)a year ago and now only cache once per month rather than weekly to save fuel. The biggest change is the type of cache I go for I now look for 1 or 2 decent ones and then aim to sweep the area of all other caches whilst I am there, this leads me more down the numbers game route rather than only going for quality caches and only sweeping areas of easy caches whern I am short of time.
