Sounds like a good time to visit Belgium. Highs in the mid-upper 50's and a bit unseasonably damp.
We had frost one morning in Bouillon back in august

, But the weather changes so fast - cold-warm-wet-sunny all in 15mins.
Ideally a place that has a super hoppy beer available, .
Look for Viven Imperial IPA or Troubadour Magma IPA, both hard to find but both nice n hoppy.
theoman found me a couple bottles of Viven Imperial IPA (Thanks again)
