If you mean Fort Collins-Loveland Municipal KFNL, then here are some comments:
Some pilots have taken to shortening "Fort Collins Loveland Traffic" to "Fort Love Traffic" so if you hear radio calls of "Fort Love", "Fort Collins", "Loveland", they are all "Fort Collins-Loveland" KFNL. CTAF 122.7 AWOS 135.075
KFNL is a non-towered airport normally; however this summer they will be basing the slurry bombers here as there is construction work on going at Metro (KBJC). So if there is a nearby fire going on, the airport may be temporarily class D with a temporary tower set up.
Be sure to check NOTAMs and TFRs.
Main runway is 33/15 with usually some practice ILS going on with 33. 33 is typically used until wind conditions greater than 4-5 knots dictate otherwise.
Cross wind is 6/24 but is short and also used as taxiway to/from the 'thru the fence' hangars.
100LL and jet A available but not the least expensive. Least expensive usually Longmont (KLMO) or Platte Valley (19V).
Lots of canadian geese around.
Heavy helicopter training at 500' AGL and reverse patterns, usually taxiway A.
Departing KFNL, head to Longmont KLMO, then south. This will put you in position to use the VFR corridor mentioned earlier. Be sure to be on correct altitude for South as this corridor is bi-directional.
