The best thing that could happen in the area would be for Glenforsa to hold 100LL ( depends if Brendan wants the trouble, but even pre positioning a few barrels would be better than nothing).

helipaddy have positioned barrels at various places for their adventures for a few years so this is possible. Andrew, at Wick, is a key POL supplier to the region. Surely something can be done if Paul is retiring
