@jandys: Aqui's advice is a good one, Bikenomad is a top choice... Also, I would post on mtb-forum.si/phpbb/viewforum.php?f=47 that you're looking for riding buddies (Czech and Slovene are probably close enough that you can navigate around the site).
@Aqui: Hi. Thanx, I will check it. Im afraid the time i want to spend here is more and more limited, but its not to far from Czech, so, maybe now, maybe later .
