I put a couple of those moisture catching thingies that comes with medication that keeps the meds dry inside the scope to suck up the moisture and was lucky the place I worked at had Nitrogen and working inside a plastic bag regassed the scope...a small pill container holds about three of them for carrying into fly in blocks, nothing worse than a fogged up scope miles from home....I think tyre shops have Nitrogen, nip down to one and re-gas it after drying it out.
