a warm (pun not intended, but it is quite hot these days!) welcome to you! I think the readers of this forum will very much enjoy your story. Till now, no one has told a story of switching from inlines to roller skates.
It is quite saddening to read your long list of great spots now closed down. But we got to move on. Maybe we need to do some lobbying to get some vert ramps built, maybe we should do more to encourange new talent to skate ramps (on roller skates, of course ;-)).
