I know how you're feeling, mustbemonroe. I have just moved to Canada from France, where I competed regularly in show-jumping with my horse.
Here, it seems that there are only western riders, and whilst I have NOTHING against western riding (infact I intend to give it a go!!), I just don't know how I am going to continue to have jumping lessons or compete.
The nearest jumping/competition yards are over 100km away and that's really unrealistic. I'm thinking that my future lies with dressage too. I enjoy dressage, but jumping is my "thing". Plus my horse is an experienced jumper, bred specifically for the job.
If you do want to do some dressage, then there is a fabulous site. Not sure if I'm allowed to post the link on here, so sorry Mods if that's the case and please delete if you have to!
Each month you have a selection of dressage tests to print off and learn. You need someone to video you and then you send your test in and you get marked and placed. It's a great way of improving, especially if you don't have access to regular lessons, but of course it won't ever replace the eventing.
Hope that helps, a little...
