Hi all from Canada and parawaiting is very popular here these days. -28 Celsius and waiting for it to warm up.
As far as finding sites to fly from, it really is hit and miss. The winter is great here because we take off from the ice covered lakes and rivers, foot launch and trikes. I've been lucky where I have been approached by curious local on-lookers near my cottage (where I was taking off from a sand pit) and came up to speak with me and ask questions. By the time the conversations were over and I was packing my gear i had received two different field location offers.
Every few months I drop in to say hi to the owners with booze in hand or an offer to help mend fences and they love it. I have also taken aerial photos of their properties and enlarged and framed them as gifts ($30 Cdn).
The number one thing to remember is to not overstay your welcome. Set up, take off and leave the area. Don't drive on their fields, scare animals, leave gates open, leave trash etc...repect is key.
Enjoy this new sport, it is a lifetime adventure!
Cheers and happy new year!
Patrick
