The environments of three asymmetric sources (B2 0800+24, NGC 4410a/b, and B2 1553+24) are studied in detail. Because the morphology of B2 0800+24 most clearly resembles the narrow-angle tails (NATs) found in clusters, this source is used to study the apparent conflict between the head-tail morphology and the low ram pressure present in a small group environment. If the jets in the NATs are ram-pressure confined, then lateral expansion of the jets in poor groups makes them easier to bend (this was observed for B2 0800+24). It is concluded that NAT morphology may be common both in rich clusters and in poor groups. 56 references.
